Plot

Sang Woo is a smart and serious programming student with a peculiar personality. He is unusually antisocial and prioritizes rational logic over human emotions. Sang Woo might be at the top of his class, but he doesnât have friends and nobody dares to approach the surly programmer. His independence is perfectly suitable with Sang Woo, who prefers to have businesslike relationships and avoid frivolous socializations.
One day, Sang Woo makes a drastic decision to remove his group members from a school project. He refuses to give them credit, labelling them as freeloaders who didnât contribute to the work. His actions have severely impacted Jae Young, a senior visual arts student and one of the accused freeloaders. Jae Young faced academic consequences because of Sang Woo. As a result, he can no longer graduate from university on schedule.
Due to his deferred graduation, Jae Young missed out on a valuable overseas opportunity. The senior student is furious and vows revenge on his troublemaking classmate. The problem is that the two of them never met face-to-face, so he doesnât know where to find his target. Sang Woo simply blocks Jae Youngâs number, keeps a low profile, and carries on with his day-to-day routine.
Sang Woo is currently creating his own video game app. Hopelessly unartistic, he works with another design student to help with the visual components. However, she quits due to other commitments in the middle of the project. Before her departure, she recommends another designer whose attractive portfolio appeals to Sang Woo. He doesnât realize the replacement is his archenemy, Jae Young.
Sang Woo and Jae Youngâs first meeting proceeded terribly. The senior art student threatens payback, while the young programmer tries maintaining his composure. In the following days, Jae Young pulls various pranks to disrupt Sang Wooâs daily habits, from stealing his classroom seat to moving in next door. Slowly but surely, Jae Youngâs annoying stunts have shaken Sang Woo, who canât get rid of this nuisance in his life. As the two students continue their ongoing feud, their feelings for each other grow heated and complicated.

Semantic Error Review
Review
Drama Review Score: 9.2

Semantic Error is a sleek and stylish BL drama that takes the viewers on an exhilarating journey. The first episode begins with a bang, setting up a juicy feud between the leads. Each subsequent episode is a fast-paced adventure, depicting the ups and downs of a volatile relationship. Along the way, we enjoy the snappy dialogue, dramatic clashes, and memorable encounters. The adrenaline in Semantic Error will get your pulse racing with enthusiasm.
I had so much fun watching Semantic Error. This three-hour series flies by at incredible speed because Iâm totally immersed in the story. The best part is the sassy dynamic between Sang Woo and Jae Young, polar opposites in every way. They frequently clash over their personality differences, but the conflict entertains me. Their arguments are cheeky, their pranks are imaginative, and their reactions are unpredictable. Thereâs an electrifying buzz when these characters interact. Iâm always excited about what theyâll say or do next.
At times, Semantic Error suffers because the plot moves too hastily. The transition from animosity to romance isnât that smooth, feeling rushed and streamlined. The storyteller couldâve dedicated more time to flesh out the sudden, drastic changes in their relationship. Nonetheless, the series gains galvanizing momentum in the second half. The scenes between Sang Woo and Jae Young are captivating as their sexual tension heats up. The climax is breathtaking when the characters finally unleash powerful bursts of passion and affection.
Both protagonists have distinctive identities. Sang Woo is a hilarious oddball who thinks and behaves so peculiarly, leading to many unexpected responses. The character is even more adorable when his emotionless façade cracks as he shows vulnerability. In contrast, Jae Young captures my attention with his bold, feisty, and vivacious demeanour. Each scene is elevated by his sparkling charisma and boisterous energy. It helps that the two actors (Park Jae Chan & Park Seo Ham) are charming, share excellent chemistry, and personify their roles perfectly.
Semantic Error is brimming with creative flair. Everything about this BL drama exudes a chic, contemporary vibe. Visually, the scenes look stunning with radiant colours, poised camerawork, and thoughtful set decorations. From a musical standpoint, the soundtrack accentuates the mood and deepens an enchanting ambiance. Iâm also a fan of the trendy wardrobe and fashionable make-up, which really brings out the physical attractiveness of the cast. Jae Young gets ten times hotter because the styling team nails his cool, edgy aesthetic impeccably.
A minor criticism about Semantic Error is the story feels a little overloaded. This series is adapted from a lengthy manhwa, which means thereâs a lot of ground to cover. Sometimes, I can feel a sense of urgency, like the storyteller wants to pack as much source material as possible. Maybe the plots could breathe more and receive richer development if there were extra episodes. Otherwise, I donât have many complaints about Semantic Error, a highly polished and presentable BL drama. I enjoyed it immensely and would love to see a Season 2 in the future.

Episode 1
Episode 1 Summary

Sang Woo and Jae Young are university students. They first meet at a school gallery, where Jae Youngâs animation work is presented. Sang Woo seems interested in the project. Although Jae Young initiates a conversation with him, Sang Woo doesnât realize heâs talking to the original designer and ignores him.
Later, Sang Woo makes a controversial decision by removing his team members from a group project. He calls them âfreeloadersâ for not contributing to the work. Jae Young happens to be one of those freeloaders. As a result, Jae Young faces academic consequences and canât graduate from university anymore. He misses out on an overseas studying opportunity because of what Sang Woo did. Jae Young is furious, vowing to seek revenge on the junior student. Yet, Sang Woo simply blocks Jae Youngâs number and continues his everyday routine.
Sang Woo is creating his own video game. His freelance designer suddenly quits because she has other commitments. Feeling guilty, she helps him find a replacement. She has arranged an interview with Jae Young, the animator Sang Woo was interested in earlier. However, Sang Woo doesnât realize he has beef with Jae Young until they meet face-to-face. The episode ends with Jae Young revealing his identity, leading to a heated showdown between the university enemies.
Episode 1 Review

This premiere is a promising start, introducing the characters and setting up their relationship dynamics intriguingly. The conflict between the leads gets me excited. Prior to this drama, I have watched the anime. However, that remake didnât explain the story too clearly, leaving me confused as a newcomer. This series has a much better beginning by comparison. I finally understand Semantic Errorâs premise!
My first impression of Jaeyoung is very positive. I love his characterâs cool, distinctive vibe with the lip piercing, the skateboard, the wardrobe, and the swagger. The actor looks great on camera, really catching my eye with his magnetic presence. I already feel charmed by him at the end of the first episode.
The final scene is filmed well. Jaeyoung and Sangwoo have a lengthy chat, which is super dialogue-heavy. However, their encounter doesnât drag at all. Semantic Error knows how to use quick cuts, snappy music, and sassy banter to create a comfortable back-and-forth exchange. Overall, this whole episode flows smoothly with fun, easygoing, and vibrant energy. I canât wait to see how the rest of the series develops.
Episode 2
Episode 2 Summary

Jae Young wants an apology from Sang Woo. However, Sang Woo refuses to admit he did anything wrong. In fact, he insults Jae Youngâs low GPA and mocks him for failing to graduate. His stubborn response riles up Jae Young, solidifying a vendetta against the programming student. âYou better brace yourself,â Jae Young whispers menacingly into Sang Wooâs ear.
After their confrontation, Jae Young begins pulling petty stunts to disturb Sang Wooâs day-to-day routine:
- He starts by buying up every coffee from the vending machine so that his enemy canât enjoy his favourite drink.
- Next, he enrolls in Sang Wooâs classes, making sure to steal his preferred seat by the window. By coincidence, they get assigned to another group project together, exasperating Sang Woo.
- Jae Young also wears obnoxiously bright red outfits, his opponentâs most detested colour.
- Jae Young insists on sitting with Sang Woo at the cafeteria, pestering him during his mealtime.
- He deliberately moves in next-door to Sang Wooâs dorm room, a drastic move that has shaken his foe.
Jae Youngâs antics annoy the typically calm and collected Sang Woo. Since Jae Young hasnât broken any rules, Sang Woo doesnât know how to stop his juvenile antics. This mental stress aggravates the serious engineering student, causing him to be irritable and have nosebleeds. Sang Woo also doesnât get enough sleep and dozes off in class. After waking up, he discovers that Jae Young has drawn doodles on his face with a marker. Sang Woo is furious and confronts his bully, insisting that he has gone too far. Nonetheless, neither party is willing to back off.
Episode 2 Review

I like the psychological warfare that Jaeyoung launched against Sangwoo. When he said the âYou better brace yourself~â line, my heart skipped a beat because I could feel a sense of danger. I didnât know what to expect, but I was a bit tense and a lot excited about the upcoming feud. And then, Jaeyoung starts pulling his stuntsâŚand theyâre all so hilariously petty. Deliberately wearing red to annoy Sangwoo is some next-level trolling and I love every moment of it. đ
Itâs fascinating to watch Sangwoo slowly lose his composure throughout the episode. He gets a nosebleed, falls asleep in class, and thinks about his enemy all the time. Even though his character wouldnât admit it, Jaeyoung has successfully gotten under his skin. Sangwoo pretends heâs mentally strong, but the poor kid is already cracking.
In the Sangwoo vs Jaeyoung dispute, Iâm on Team Sangwoo. Although I wouldnât have done what he did with the group project, itâs Jaeyoungâs own fault for being lazy and not maintaining good grades. With that said, Sangwoo is stubborn. He mightâve resolved the conflict with an insincere apology. Instead, he worsens the situation by insulting Jaeyoung and making an enemy in him. Sangwoo pours fuel over the fire and then wonders why Jaeyoung hates him so much lol.
Episode 3
Episode 3 Summary

In Episode 3, Sang Woo takes drastic measures to stop Jae Young from annoying him:
- First, he buys his favourite coffee in bulk to avoid the vending machine problem.
- Next, he shows up hours before class to secure his preferred seat by the window.
- When Jae Young sits beside him, Sang Woo puts up a tiny partition in between their desks to separate them.
- At lunch, Sang Woo deliberately sits in a crowded table with strangers to avoid sitting alone with his tormenter.
Jae Young is amused he caused these erratic changes in his enemyâs behaviour. However, Jae Youngâs friend Yu Na feels perplexed. She doesnât understand what her friend is trying to accomplish with these silly pranks. Yu Na wonders if Jae Young is picking on Sang Woo because of a crush.

Meanwhile, Sang Woo and his classmate Ji Hye grow closer. She gives him the pet nickname of âSang Chuâ (aka. Lettuce). Obviously, she has a crush on him, but Sang Woo doesnât respond or reciprocate these feelings. Ji Hye mistakenly assumes that Jae Young is his friend. Sang Woo clarifies they donât have any relationship.
Jae Young discovers that Sang Woo has signed up for a class, led by a notoriously awful lecturer. Jae Young tries to give a warning, which gets ignored. Later, Sang Wooâs new teacher takes his students to a bar. When Sang Woo wants to leave early, the drunken lecturer gives him a tough time. Their tension almost escalates to a physical brawl, but Jae Young steps in to protect Sang Woo from getting hurt.
Episode 3 Review

The theme of Semantic Error is about how Sangwoo, a very rational person, starts acting irrationally because of Jaeyoung. For example, Sangwoo shows up in an empty classroom at 6:30AM and feels delighted about âoutsmartingâ his enemy. He also puts up a divider in between their desks, even though it practically makes no difference at all. In programming terms, Jaeyoung is like a glitch in the system that causes Sangwoo to malfunction.
To be honest, I donât really know why Jihye has a crush on Sangwoo? Her character shows up from Episode 1 and starts hitting on him out of the blue. Her scenes always feel a bit random and extraneous to the plot. With that said, I understand Jihye serves a purpose in the story, allowing Sangwoo to interact with another character besides Jaeyoung. We get to see him behave more naturally (or as natural as Sangwoo can be đ ) in his chats with Jihye.
Although I enjoyed the first three episodes, the BL content in Semantic Error has been pretty light so far. Weâre almost halfway through the series, yet the two leads are still pretty much enemies. I have doubts whether this drama can turn their hostility into a persuasive romance with the remaining time left. As a BL watcher, Iâm getting antsy around this point, knowing there are only 8 episodes. When will the relationship scenes start?
Episode 4
Episode 4 Summary

After the fight, Jae Young cannot return home since his keys & belongings are left at the bar. Surprisingly, Sang Woo allows him to enter his room and contact his friends with a laptop. Despite their animosity, he thanks Jae Young for defending him in the fight. Later, Sang Woo puts medicine treatment on Jae Youngâs arm injury. Their amicable interactions are the first sign of a truce between the two former enemies.
This episode marks a turning point in Jae Young and Sang Wooâs relationship. Since then, Jae Young has stopped wearing red clothes and tormenting Sang Woo. Jae Young is remarkably friendlier as they work together on the group project for the French class. Sang Woo still doesnât trust his former enemy, wondering if this fraternization is a new tactic. Jae Young insists he doesnât have any strategy and only acts from his heart.

The two leads are in the library together, where Jae Young has fallen asleep. Suddenly, Sang Woo thinks of a naughty idea. He picks up a pen and wants to draw on Jae Youngâs face as payback for his previous prank. However, Jae Young wakes up and catches him in the act. Sang Woo feels embarrassed, questioning why he did something so childish and out-of-character.
Itâs the day of their class presentation. Jae Young has picked over-the-top costumes for them to wear. Sang Woo reluctantly goes along with the theatrics. They end up giving a successful presentation. Later, Sang Woo is mortified to learn that Jae Young stole their costumes from the drama club. They sneak into the clubroom to return the clothes, but almost get caught. The episode ends with their characters in hiding, standing very close to each other. Jae Young leans in, almost seemingly initiating a kiss.
Episode 4 Review

This episode looks pretty! The cinematography has taken a step up, producing even more gorgeous visuals than usual. I love that mesmerizing close-up shot of Jaeyoungâs face where he opens his eyes and flashes a smile. Be still, my heart. And did you see him strutting around campus in a black leather jacket? Woof. The Semantic Error styling team knows how to dress him up well. đ
I like how the characters change their wardrobes to mark the evolution in their relationship. Youâll notice that Jaeyoung stops wearing obnoxiously red clothes since he doesnât want to torment Sangwoo anymore. Likewise, Jaeyoung makes subtle changes to his fashion choices. This episode is the first time he doesnât wear a cap after Jaeyoung complimented his hatless look. Plus, we see him wear brighter colours besides blacks and greys all the time. Sangwooâs pastel blue sweater is a sign of Jaeyoungâs positive influence.
I enjoyed many of Jaeyoung and Sangwooâs delightful interactions in this episode. Their arguments and pranks were amusing, but Iâm glad that weâve moved on to the next phase of their relationship. With that said, the change from their feud to their romance came suddenly. Just last episode, Sangwoo still hated his enemy with a passion. Now, weâre supposed to think he loves Jaeyoung? I feel like Semantic Error shouldâve spent more time developing the feelings between these former enemies. The transition seems rushed and could be a lot smoother.
Episode 5
Episode 5 Summary

Sang Woo runs away from his close encounter with Jae Young in the clubroom. The programmer feels so tense that he doesnât even show up for class, a rarity for him. Sang Woo searches online about a âbiological disorderâ that would explain why his nervousness. Jae Young is worried and wants to know whatâs wrong. Sang Woo acts agitated and gives an aggressive response. They have a heated argument, concluding with Jae Young storming off angrily.
After their confrontation, Jae Young completely cuts himself out of Sang Wooâs life. He doesnât show up for classes or return to his room. Sang Woo is bothered by Jae Youngâs sudden absence. Ji Hye notes that he has acted spacey lately. She uses programming terms to give him advice on troubleshooting his problem.
Sang Woo stalks Jae Youngâs Instagram page, secretly bookmarking all the attractive pictures. He discovers Jae Young has a new part-time job at a restaurant. When Ji Hye asks him out for lunch, he brings her there as an excuse to spy on his crush. Ji Hye is excited since she thinks theyâre on a date. However, Sang Woo is preoccupied searching for Jae Young and demands a serious chat with him.
Episode 5 Review

My favourite moment of the episode is when Sangwoo saves Jaeyoungâs Instagram pictures and gives commentary. âHe thinks heâs so cool, huh?â *saves pic* âHow silly.â *saves pic* He says moodily while screencapping every adorable photo of Jaeyoung to store on his laptop. đ BTW, you can follow Jaeyoung (zzang_jae_0_0) and Sangwoo (choosangwoo_) on IG, bookmarking their pics on your computer too~
Oh my god, Sangwoo and Jaeyoungâs relationship is so up-and-down. These two were finally on friendlier terms in the last episode, but now they have gone back to feuding again. Like, I just got used to the idea that they arenât enemies anymore. But oh wait, they hate each other once more. Their volatile relationship swings too much like a pendulum. I wish we couldâve seen them getting along for a while before they had another fight.
Is Jihyeâs only role in this drama to flirt unsuccessfully with Sangwoo? He has given zero inclination about showing any romantic interest in her. Iâm not sure why this girl is so adamant about forcing a relationship from start to finish. What is the basis of her attraction? Is it because he gave her change money that one time? It was so embarrassing when their characters went out for lunch and Sangwoo paid no attention to her. When will Jihye get a hint and realize sheâs barking up the wrong tree?
Episode 6
Episode 6 Summary

The characters chat outside the restaurant, where Sang Woo asks Jae Young to work on his video game. Jae Young is still upset about their past argument, so he refuses the job offer. Sang Woo accidentally left behind documents related to his video game. Jae Young is surprised to see Sang Woo has kept his doodle from their first meeting. When they meet later that night, Sang Woo asks again whether Jae Young could be his game designer. This time, Jae Young agrees.
They begin working on the game. Sang Woo proves to be a tough employer, pushing tight deadlines for the art assets. Jae Young is sincere about his work, staying up overnight to revamp the character designs. Sang Woo is pleased with the art. As a reward, he pats Jae Young on the head, an affectionate gesture that takes the recipient by surprise. Afterwards, they continue working closely. Yu Na teases them when she overhears their banter, signifying they have grown their bond.

Jae Young is curious why a genius programmer wants to make a game instead of working at a company. Sang Woo likes the accomplishment that comes with creating a project from scratch and bringing his vision to life. The answer inspires Jae Young, who asks if he can pat Sang Wooâs head. His proposition is accepted. Earlier, Sang Woo stated he didnât like being touched without warning, and Jae Young has respected his boundaries since then.
In the final scene, Jae Young takes a quick power nap from working. Sang Woo contemplates as he observes his sleeping colleague on the sofa. Impulsively, he plants a kiss on Jae Youngâs lips before dashing out of the room in embarrassment. Sang Woo opens his eyes afterwards, shocked by what just happened.
Episode 6 Review

OMGGG THE FIRST KISS. Honestly, I was shocked and didnât see this moment coming. đ˛ That scene leading up to the kiss is visually enchanting. The close-up shot of Jaeyoungâs face looks so handsome with his long eyelashes, pink lips, and warm lighting on his face. Jaeyoung exudes an ethereal aura, almost like heâs Sleeping Beauty. Semantic Error is excellent at creating this lush ambiance to accentuate its love story.
Whatâs the standard reaction when someone pats you on your head for doing a good job? Personally, I screamed a little in excitement when Sangwoo touched Jaeyoungâs head. AHHH YESSS!!! đ The moment is surprisingly intimate and endearingly awkward. Sangwoo makes a clumsy attempt at human interaction, but he has no idea how and doesnât quite hit the mark.

I like the height difference between Sangwoo and Jaeyoung. Sangwoo is smaller and shorter than his love interest, so his character looks up every time they interact face-to-face. This arrangement works because it makes him appear vulnerable. When Sangwoo stares upwards with those pleading eyes, he seems more delicate and sensitive. You can see through his bravado and reach the emotional side of him. Not wearing his cap also lets us view his eyes clearly, another defence mechanism removed.
This episode explores the power dynamics between the characters. Jaeyoung gets angry in an earlier scene when Sangwoo drops the honorifics around him. So, Sangwoo consciously makes an effort to use the terms again in their next exchange. This gesture emphasizes his characterâs sincerity, as heâs willing to be respectful and defer to his senior. Earlier, Jaeyoung called him out for acting like an emotionless robot. Hereâs Sangwoo now, trying his best to behave more sensitively and tactfully.
If Semantic Error had a longer length, I wish we couldâve seen more of the video game development. Sang Wooâs game is a significant part of the series, but the details are vague. I barely know anything about Veggie Venturer. I think it might be an action-adventure video game with vegetables as characters, but who knows? I want in-depth content related to making the game, or at least learn Sang Wooâs inspiration and thought processes.
Episode 7
Episode 7 Summary

The characters are alone in an empty bar, where Sang Woo has gotten drunk. He pretends their kiss from the last episode didnât happen. Their chat shifts to Jae Youngâs appearance, and Sang Woo admits to finding his colleague attractive. His reply prompts Jae Young to be daring. âWarning. Iâm going to kiss you in one minute,â he whispers seductively. Surprisingly, Sang Wooâs response is to pull in Jae Young for a kiss.
After a short pause, the characters make out more passionately in their second attempt. Yet, Sang Woo feels insecure and thinks they made a mistake. He apologizes for kissing Jae Young the first time, but insists they shouldnât get romantically involved. Sang Woo is worried about hindering their work on Veggie Venturer. Jae Young disagrees and believes they should start dating. He suggests they do a two-week trial for a romance. Sang Woo needs time to think before making a commitment.

As the characters spend time apart, they have various conversations:
- Jae Young and Ji Hye have a heated chat, addressing their rivalry over Sang Woo. Jae Young warns her to stop using the Sang Chu nickname, which feels too intimate.
- Sang Woo asks Yu Na about Jae Youngâs romantic history. She emphasizes her friend dated many people, but his past relationships failed because Jae Young lost interest.
Sang Woo becomes curious about the tattoo on Jae Youngâs arm. Jae Young uses the marker to draw a picture on Sang Wooâs arm. Itâs the same video game mascot from their first meeting. Afterwards, they chat about the two-week trial. Jae Young teases him with a saucy preview, which includes holding hands & kissing. Finally, Sang Woo accepts the trial and wants to date Jae Young. However, the episode ends on a cliffhanger. Jae Young receives a job offer at an overseas company, which means their romance is disrupted before it could start.
Episode 7 Review

Sangwoo and Jaeyoungâs kiss in this episode is a showstopper, taking my breath away. I love the flirtation at the start, building up the sexual tension between the leads. The adrenaline is unleashed in a memorable kiss, like a powerful burst of desire. The chic and moody ambiance adds to the passion, particularly during the confrontation in the alleyway. Semantic Error has pulled off a divine BL moment where everything clicks together, from the artistry to the chemistry. WOW.
I enjoy the two other relationship moments in this episode, both powered by juicy BL material. When Jaeyoung draws a tattoo on Sangwooâs arm, the gesture feels intimate, like a small imprint of his love. Initially, I couldnât visualize a suitable tattoo for Sangwoo, but the video game mascot is a clever choice. The scene where Jaeyoung gives Sangwoo a relationship preview is also fantastic. âYou get to hold my hand, we already kissedâŚâ His voice drifts off as he pulls in Sangwoo for an embrace, leaving the rest to the viewersâ powerful imagination.
I love how Sangwoo speaks. Hereâs what he says about starting a relationship with Jaeyoung: âIâll announce the results of my analysis.â Why does Sangwoo talk about romance like heâs giving a lab report? đ After a moment of self-reflection, he corrects his phrasing to, âWas that too formal? Iâll accept your proposal, we can do a trial run.â Sangwoo looks satisfied after practicing this line, as if his new businesslike response is any better. Just say you want to date him using ordinary, everyday language! Stop acting like a robot! đ
Episode 8
Ending Explained

Semantic Error has a happy ending where Sang Woo and Jae Young become a couple. Although Jae Young is recruited for a job in France, his first instinct is to turn down this opportunity. He chooses to stay committed to Sang Woo and finish their game together. However, Sang Woo isnât happy about holding back his partner. He refuses to start a relationship with Jae Young and wants him to pick the job offer instead.
Sang Woo and Ji Hye meet up. She confesses her feelings, but already knows that he isnât interested in her. Ji Hye isnât devastated and feels proud of herself for being honest. When Sang Woo apologizes, Ji Hye is surprised by his empathetic response. She thinks falling in love has changed his personality, making him more attuned to peopleâs emotions.

Sang Woo has a change of heart and wants Jae Young to stay with him after all. They meet in the middle of the night, where Sang Woo initiates a spontaneous kiss. Jae Young reveals he never planned to leave right now. He already told the company about his commitments to Sang Wooâs video game. Ideally, they might defer the job offer until later. If not, Jae Young is still confident heâll find a better job in the future. Now that Sang Woo and Jae Young are on the same page, they officially become a couple.
The final scene shows Sang Woo and Jae Young hanging out in the bedroom, flirting lightheartedly. Jae Young discovers his boyfriend keeps a secret folder of his photos on the laptop. This revelation embarrasses Sang Woo and the couple has a playful scuffle on the bed. Their exchange ends with Jae Young kissing his boyfriend tenderly. The last shot of the series is a tablet screen, which says the semantic âerrorâ has been cleared.
Ending Review

The conflict over Jaeyoungâs job offer echoes the predominant themes in Semantic Error. Picking the corporate job seems like a rational decision since it offers higher pay & better opportunities. In contrast, working on an indie game is based on sentimentality. This smaller project is closer to your heart, something you sincerely believe in creating.
I like this storyline because it challenges Sangwooâs core values, asking him to choose between logic versus emotions. His brain tells him that Jaeyoung should take the job offer, but his heart says otherwise. The old Sangwoo wouldnât experience this struggle because he simply thought like a machine. After falling in love, his character becomes more sophisticated. Ultimately, Sangwoo learns to prioritize his personal feelings over what seems like the logical choice.
The post-credit scene has me in stitches when Jaeyoung discovers Sangwooâs secret folder of photos. đ I also love their final kiss, a sweet and affectionate gesture that caps off the series endearingly. Yet, itâs a shame Semantic Error ends at this point because Iâd love for the story to continue. I want more episodes, more storylines & more BL content between this couple. Letâs strike the iron while itâs hot! Unfortunately, we wonât get Semantic Error Season 2 in the near future. BL fans must wait until Jaeyoungâs actor finishes his military service. đ˘
Semantic Error Anime Series
Anime
Semantic Error (2021)

An anime remake of Semantic Error was released in 2021. Itâs a painfully short series that you can complete in fifteen minutes. Instead of telling a cohesive story, the anime only adapts several random, disjointed scenes. You arenât introduced to the characters or their dynamics properly, which can be confusing for new viewers. The first episode (and maybe the second) is included in the live-action remake.
The live-action series is the superior version of Semantic Error. Thereâs simply no contest. Itâs unfair to compare a three-hour drama to a fifteen-minute anime, but the differences are significant. Although the Semantic Error anime is steamier, everything else is not as polished or cohesive as the live-action adaptation. After watching this drama, I realize the anime has many shortcomings and lacks a lot of content. You donât have to go out of your way to see the remake if youâve already watched this series.
Semantic Error Interviews
Interviews
Youâll have to excuse me. Since finishing Semantic Error, I have fallen into the quicksand of everything to do with Jae Youngâs actor Park Seoham. đ I have consumed every cast video and translated interview about Semantic Error, giving me newfound appreciation over this series. I love learning about the actorâs journey, laughing at his goofy antics, and just staring at his handsome face.
I have compiled a list of my favourite interviews for Semantic Error. Thereâs a mixture of videos, tweets, and news articles, including a small excerpt from each interview. All translations should be credited to the original authors in the provided links, thanks to their incredible work!

Park Seoham
At first, because Jaechan was young, I just saw him as young. I was like, âso cute!â But as we went along, thereâs so much that Iâm learning from him. Heâs deeply thoughtful and kind-hearted.

Park Seoham
I went to the filming with low self-confidence. The producer even asked why are you intimidated? But Jaechan gave me confidence. Whatever I did, Jaechan would say, âHyung, you really seem like Jaeyoungâ and complimented me. I was thankful for that.

Kim Su Jeong
I said this after the second meeting. Between the two actors, I felt that if it wasnât the two of them, I donât think I would be able to go on.

Kim Su Jeong
On the last day, I nearly teared up seeing how Seohamâs script was in tatters. He worked really hard. He would always come first during the rehearsal and check the positions. He also worked harder than anyone in researching his character and practicing.

I was really exhausted and thought I would retire. After I left KNK, I wasnât confident in doing activities alone and I didnât have the confidence to do anything more in the future. I became more energized on set. During the filming and even as filming ended, I said thank you for helping me find my dream again.

Park Seoham
A lot of people want a Season 2 and I also want a Season 2 too. Even though the time Iâll be away is long, a lot of people say I will wait for you. Seeing those words, I really need to come back better. I will definitely become better. Iâll leave with a thankful heart and come back with tears.

There are many people against same-sex relationships, and I hope this drama can serve a gatefway for eliminating that prejudice.

Before starting, the fans of the original were very angry. At the time, I was like, can I satisfy the fans of the original? However, after completing the casting and watching the actors perform, I was convinced that I could create a drama with its own charm.

The production crew, including the writer, director, and marketing team, are all women. Thanks to this, we made Semantic Error with a good understanding of what female viewers like.

Game #1
Around 10 minutes
In this video, the two Semantic Error actors play a game together. They must guess the mystery items inside the box by only using their hands. The first person to guess correctly can draw a doodle on the other personâs face. Jae Youngâs actor (Seo Park Ham) gets spooked pretty easily by some of the most harmless materials. đ
Game #2
Around 17 minutes
In this video, the two Semantic Error leads play various mini-games with each other. Each actor is given a buzzword and must describe it to their costar without spoiling the answer. The video concludes with sentimental messages about what Semantic Error means to each actor.

Watcha

Watcha (ěěą ) is a Korean studio that made the 2022 BL series Semantic Error. Watcha is an entertainment streaming platform in South Korea, occasionally producing some original BL and non-BL dramas.
I really enjoy your reviews. Semantic error was perfect, maybe the only flaw was that is too short. That is my new favourite Korean drama ^^
Thank you for reading my reviews! Yes, I love Semantic Error too, but wish the story could continue with more episodes. It’s still one of my favourite BL dramas and I really, really hope there’s a Season 2. đ
Great review! I really loved this Semantic Error adaptation. As someone who’s read the manhwa this did a pretty good job in keeping the feel of it. I Loved the actor’s potrayels and chemistry. I feel like my only thing is they went a little fast. Like by episode 4 I was like “Woah we’re already here?” which is good and bad because it got rid of the slow parts of the manhwa but it also like you said kinda made it feel overloaded and the romance feel sudden.
But for the most part to adapt like 50 chapters into 8 episodes I thought it still did a good job. Really happy about the ending since the Manhwa isn’t over I was really worried they were gonna send Jae Young to France. Hope there’s a season 2 though I really love this series.
omg, another great review from bl watcher .. we love to see that!!
semantic error is definitely one of my favourite bl dramas now. it’s been a long time since i enjoyed a good bl kdrama. this bl kdrama is amazing in almost every way. sadly it was too short, but im so glad the duration was more than 20 minutes for most episodes. I ABSOLUTELY ADORE SANG WOO AND JAEYEONG’S RELATIONSHIP. ITS SO CUTE AHHHH and both leads did SO GREAT in the acting and had great chemistry. jaechan is so stunning hehe. omg the kissing scenes were so intimate and realistic, it was really nice to see. THE HUG DURING THE CONFESSION, TOO ADORABLE LIKE.
also i love how the girl who liked sang woo handled his regection, she was brave and understanding. i love her for it. south korea is back on its feet with BL. i hope to see another season, i cant get enough of it. i hope to see new korean bl dramas that can capture my heart like semantic error did.
