Sangwoo and Jaeyoung stare into each other's eyes in the Semantic Error anime series.

Adapted from a Korean novel, Semantic Error is a slice-of-life BL anime series with four short episodes. The main characters are two university students working on a video game project together. Despite their drastically different personalities, the attraction between them is palpable.

I liked what I saw in the Semantic Error anime, which showed tons of promise with an engaging romance. However, the series is frustratingly short at just fifteen minutes long. Any storytelling feels abbreviated, like I’m watching an incomplete remake that only covers a small part of the source material.

Semantic Error Anime Review

Review

Anime Review Score: 6.4

C
Sangwoo and Jaeyoung kiss each other.

Semantic Error is an intriguing slice-of-life anime that shows much potential. However, this series is painfully short at just fifteen minutes long. Although the narrative is quick and basic, the BL content still manages to be pretty engaging. The story is told through four loosely connected episodes, each depicting a juicy and passionate moment between the main characters. I’m pleasantly surprised by Semantic Error, captivating me with the two likable protagonists and their sizzling romance. 

As someone unfamiliar with the Semantic Error manhwa or novel, I don’t know how this adaptation fares compared to the original. My impression is the anime seems like a very stripped-down version of the source material. For instance, we never get formal introductions to the characters. We only learn about their relationship dynamic through visual cues or random snippets of conversations. I’m sure the Semantic Error remake leaves out many other crucial details, since the gaps in the narrative feel quite noticeable.

Despite having almost no context, I still enjoy the sexy rapport between Sangwoo & Jaeyoung. The anime successfully cultivates a fun, flirty vibe between the characters. Their foreplay builds up quickly and convincingly, so it doesn’t take long before they share intimate kisses or indulge in erotic exchanges. Their physical affection is also balanced with scenes that develop the emotional bond between the couple. Semantic Error does an excellent job at solidifying the BL romance, an incredible feat in such a short amount of time.

Sangwoo and Jaeyoung have attractive character designs. They can look rather dashing in some scenes from specific angles. However, the rest of the visuals are unremarkably plain. Plus, the art quality is inconsistent across the episodes, fluctuating between average and a little half-assed. You can tell this anime was made with limited resources, evident through its lack of polish. I’m sympathetic to the low-budget constraints and won’t dock many points from my review. Nonetheless, it’s regretful that Semantic Error couldn’t look more beautiful.

Semantic Error has an impressive last episode, a delightful showcase of what this anime could’ve achieved with enough time and budget. As much as I like what I see, the problem is that I only get a glimpse instead of the full picture. This series is simply too short and lacks cohesive content. It desperately needs extra episodes, ongoing plots, along with adorable relationship moments. Overall, Semantic Error captures my interest, but I suspect that’s due to the strength of the original story. Otherwise, the anime leaves me feeling unsatisfied and wanting a lot more.

Summary

Lack of story

There’s barely a cohesive narrative in the Semantic Error anime. Instead, the anime adapts random, disjointed moments from the manhwa. It’s confusing if you don’t know the source material.

Sizzling romance

Surprisingly, the anime establishes a steamy and sexy romance between the leads in a short amount of time. There are strong displays of physical and emotional affection throughout the four episodes.

Basic visuals

While I enjoy the character designs, the visuals look plain and aren’t consistently well-drawn. It lacks a bit of polish, falling below average quality.

Decent ending

I loved the final episode in the anime, capturing the essence of BL elegantly. I just wished there were more episodes like this one.

Okay artistry

Some of the steamier scenes are illustrated well with titillating shots and sexy ambiance. While you don’t see anything explicit, I like the groove and vibe of those erotic moments.

64%

Unfortunately, the Semantic Error anime series is too short at a fifteen-minute length. The tiny episodes aren’t enough to build a coherent or engaging narrative in that limited time.

Episode 4

Sangwoo and Jaeyoung roleplay as the genie in Episode 4.

Episode 4 takes place on April Fool’s Day. Incidentally, the actual episode was also released on April 1st. The plot is straightforward. Jaeyoung plans a tiny scavenger hunt around the apartment to surprise Sangwoo. His prize for completing the scavenger hunt is Jaeyoung dressed as a genie, and he will grant Sangwoo three wishes to his heart’s desire.

Naturally, my mind jumps to the naughty wishes right away~ 😙 However, that’s not what ends up happening. Jaeyoung uses his ~three wishes~ pragmatically, instructing his boyfriend to wash dishes, organize the shoe closet, and run ordinary household errands. The episode ends really adorably as Jaeyoung wishes for the genie to turn back into his boyfriend. Oh my gosh, that cute moment put a huge grin on my face.

I was REALLY impressed with this episode. It’s the exact type of short self-contained story that I wanted from this anime. Give me ten more episodes like this one and I would be satisfied with the Semantic Error series.

Remake

Semantic Error has a live-action adaptation. This eight-episode BL drama was released on February 16, 2022. Its final episode concluded on March 10, 2022.

Semantic Error 2022 live-action series Drama review

Semantic Error has a live-action remake released in 2022.

In addition to the anime, Semantic Error has a live-action adaptation released in 2022. This Korean BL drama has eight half-hour episodes, and you can finish the entire series in around 3 hours. As you can imagine, this version has way more time to expand on the plot, characters, and romance.

My opinion of the Semantic Error drama is very positive. The story and characters are introduced properly, giving me actual context to Sangwoo and Jaeyoung’s relationship. If anything, the drama actually makes the anime worse because it highlights the glaring deficiencies. However, it’s probably not fair to compare a three-hour drama with a fifteen-minute anime. The limitations are obvious and you know which version will be superior. Regardless, I highly recommend the Semantic Error series!

  1. When it comes to making webtoons in to anime, I think a lot of times they are just trying to make quick money I love this webtoon so much and cant wait for the 3rd season. If they only gave it as much time and effort as they did to the webtoon this would have been a great anime. And this goes for all the others animes that were first webtoons.
