Plot

Yoo Han helps Yeon Woo discover the many beautiful colours in his life.

Yeon Soo is a high school student with a rare disability that affects his vision. He has a unique form of color blindness, nicknamed as “mono”, which allows him to see colour only when he is around his soulmate, also known as a “probe”. In society, monos have gotten a negative stigma since they tend to develop an obsessive codependency with their probes. For this reason, Yeon Soo is often lonely and misunderstood. He even got kicked out of his last school after fighting someone who made fun of his illness.

At his new school, Yeon Soo is overwhelmed when he meets his classmate Yoo Han, who just happens to be his probe. Whenever Yoo Han appears around him, Yeon Soo can see all the vivid and vibrant colours in his surroundings. Unfortunately, the colours fade away as soon as Yoo Han is gone and his vision returns to a bleak monochromatic palette.

Yeon Soo tries to avoid Yoo Han, out of fear for the psychological repercussions if he gets too attached to his probe. However, the flirtatious Yoo Han takes an immediate interest in his new classmate, finding him handsome and intriguing. Yoo Han is determined to spend time with Yeon Soo, showing him different facets of the colourful world around him.

Ending

★★☆☆

Yoo Han takes Yeon Woo on small adventures to show him the colours in the world.

Color Rush had a strong start and immediately hooked me with its creative premise. I was interested in exploring Yeon Woo’s condition and how much meeting Yoo Han would affect his everyday life. My heart stirred in the early scenes when Yeon Woo saw colour for the first time, only to lose this ability right away. By the end of the first episode, I was already attached to this character and felt emotionally engaged with his storyline. I was rooting for Yeon Woo and wanted him to find joy in such a bleak, colourless world.

Unfortunately, I don’t think Color Rush reached all of its tremendous potential. Its short length is a huge limitation. With just eight tiny episodes, the series never explores its interesting plot in too much depth, just grazing over the some of the storylines lightly and quickly. Color Rush does have a handful of moments that are particularly well-executed, but they also could’ve done so much more with the material. I wanted more moments, more scenes, and just more substantial content from Color Rush.

Color Rush also suffers in a lack of character development for Yoo Han. They do a fantastic job with Yeon Woo’s characterization, but the other main character got seriously sidelined, not existing outside of his relationship with Yoo Han. I’m skeptical of the romance between the two characters. I can’t overlook the power imbalance, the obsessive tendencies, or the emotional manipulation in their dynamic. Sometimes, it feels like Yeon Woo and Yoo Han are using each other instead of being in love together.

Nonetheless, Color Rush still managed to tug at my heartstrings with some emotionally powerful scenes. Yeon Woo’s actor is a standout, conveying his anguish and despair with remarkable authenticity. The scene where he cried after seeing his mom’s portrait in colour was an incredible performance. Any time his character is suffering (which happens a lot), he does a great job at breaking my heart.

Color Rush’s premise is so strong that I can look past some of its flaws and still find the series enjoyable. With a complex main character, some emotional scenes, and great acting performances, this is an above-average BL drama definitely worth a watch.

📖 How is the story?

Great story

Color Rush has a super engaging premise, one that was presented really well in the start. In addition to Yeon Woo’s complex health condition, there’s also an overarching mystery about what happened with his missing mom. I was so impressed with the story’s creativity and couldn’t wait to see how it develops.

As the plot progressed, I did feel a little frustrated because Color Rush barely scratched the surface with its storytelling. By the time those eight episodes flew by, I wished the drama could’ve done more with its immense potential, especially with the unresolved mystery about his mom.

💕 How is the romance?

OK romance

I was skeptical of their romance and couldn’t get fully on board, even in the end. While some of their scenes together were beautiful and poignant, this relationship had an unhealthy dynamic. It seemed like Yeon Woo only cared about Yoo Han because of the powers he induced, even though Color Rush depicted this as “romance”.

Meanwhile, Yoo Han danced a fine line between being eager to help someone with a disability and being predatory toward someone who is emotionally vulnerable. He gave me reason not to trust him or his intentions with Yeon Woo.

🎭 How is the acting?

Good acting

Yeon Woo’s actor was excellent, and he showed some serious acting chops during the big emotional scenes. However, I found Yoo Han’s actor a bit underwhelming and he was stiff in some parts.

😎 Who’s the best character?

Yeon Woo

Oh, easily Yeon Woo. His actor (Yoo Jun) carried the entire drama with a strong, nuanced performance. It’s hard not to get emotional every time Yeon Woo talks about only seeing the greyness in his life. This young, capable actor did a fantastic job at making Yeon Woo a complex and vulnerable character.

🍆 Is there any nudity?

No nudity

Nope, everyone is dressed to the nines and remains buttoned up. They’re usually in their school uniforms. You won’t see any display of skin whatsoever on Color Rush.

🎯 Are there any triggers?

Suicide

Yes, some of the storylines are heavy. There’s a murder, a missing mom, and a suicide attempt. Yeon Woo also indulges in some dark, obsessive thoughts about hurting and kidnapping Yoo Han.

⭐ What’s the best part?

Yeon Woo

I loved Yeon Woo’s emotional journey, which was sad and heartbreaking from start to finish. I have some (minor) vision problems myself at a young age, so I always feel more drawn to characters going through this particular type of hardship. Watching Color Rush made me reflect a lot introspectively. I felt tremendous sympathy for Yeon Woo’s character and his internal struggles.

📝 What would you change?

Yoo Han

Yoo Han remained too much of an enigma throughout the series and could’ve benefited from more character development. I don’t mind Yeon Woo got most of the focus, but Yoo Han was so underdeveloped that he seemed like a prop for the plot rather than a fully realized character. Color Rush could’ve expanded on his family background or his K-pop trainee aspirations.

Color Rush Episode Guide

Episode Guide

Episode 1

If you were Yoo Han, would you feel offended or flattered if Yeon Woo fainted after seeing your face?

This episode introduces us to Yeon Woo and his colorblind condition. After transferring to a new high school, he meets Yoo Han and immediately faints after seeing his face. In the nurse’s office, Yeon Woo sees colour for the first time, when both characters realize that Yoo Han is his “probe”. Unfortunately, Yeon Woo’s powers don’t last long and the colours fade away again.

  • Best moment: The scene where Yeon Woo saw the colour of his pants for the first time made me feel things. Why is it the first episode and I’m crying like a baby already? 😭
  • Worst moment: Oh my god, the shoddy visual effects with the colours certainly need some getting used to. For a moment, I thought my computer was glitching out because the scene looked so weird. Color Rush usually does a pretty good job concealing its low-budget production, but they dropped the ball here with the primitive CGI.
  • My thoughts: Honestly, I was so impressed with the quality of the first episode. I guess I’m not used to a BL drama having such a high-concept premise, but I was completely absorbed into the plot. This was a strong opening that introduced multiple interesting storylines with lots of potential. It felt like those fifteen minutes flew by in the blink of an eye.

Episode 2

Yoo Han is determined to teach Yeon Woo all about colours.

To Yoo Han’s surprise, Yeon Woo wants nothing to do with him and doesn’t want to restore his vision. He believes any relationship between mono and a probe will only end badly, even citing extreme examples of murder and kidnapping.

However, Yoo Han is determined to teach Yeon Woo about colours, forcing his powers on him no matter what. Yeon Woo ends up appreciating the beauty of the colour spectrum and wants to learn more.

  • Best moment: Yeon Woo’s inner monologue gave us great insights into his thought process. I loved it when he described the different shades he see: white, snowy white, light gray, silver gray, moonlit gray, cement gray, dolphin gray, shark gray, charcoal gray, and black. As someone who only thinks of these colours as ‘white’, ‘black’ & ‘gray’, Yeon Woo’s description offered a more nuanced look into his point of view.
  • Cute moment: When Yoo Han asked Yeon Woo to look at him, and Yeon Woo was being a sulky tsundere with daggers in his eyes, and Yoo Han teased him with the line: “Look at me. I said look, not glare.” That line delivery made me laugh. 😆
  • Worst moment: The scenes with Yoo Han’s classmates, are they that necessary? I don’t really get the whole elaborate anecdote with the old man or basically anything they say. I know they’re just trying to be friendly, but these guys are a little annoying. When Yeon Woo said he doesn’t want to be friends with them, a part of me was secretly relieved because it meant less screentime with them.
  • My thoughts: I feel so bad for Yeon Woo and really sympathize with him. 😢 At first, I was surprised that he wouldn’t make use of Yoo Han’s ability, but it also made sense that he wanted to protect himself and not get his hopes up. Of course, we wouldn’t have a story if Yeon Woo didn’t change his mind in the end of the episode. I’m excited at the prospect of Yeon Woo discovering more of the beautiful colours around him.

Episode 3

Yeon Woo was so happy when Yoo Han showed him the colours of the prism on the wall.

Yoo Han takes Yeon Woo into a dark room and shows him the colour effects from a prism. Yeon Woo is amazed by the visuals and wants to see more, but the mood takes a dark turn when Yoo Han refuses to help him.

Later, Yeon Woo’s mind begins to spiral, as he becomes fascinated with a news story of a mono killing his wife in an obsessive fit of rage.

  • Best moment: The sheer joy of Yeon Woo seeing the colours in the prism was so, so precious. Something that feels so ordinary to the rest of us is actually remarkable for a colorblind person like Yeon Woo. While this scene was shot in a very low-budget way, it still managed to convey the message quite well, I think.
  • Intriguing moment: Yoo Han had a memorable line in this episode: “The colours of this world are yours to enjoy, only when I let you see them.” I’ve been on the fence with Yoo Han’s character, but this line confirmed to me that he’s an emotionally manipulative jerk. Lording your powers over someone with a disability isn’t as cool as you think it looks. 🙄 I don’t hate this moment though, because it does make their relationship dynamic more interesting. There’s a clear power imbalance between the two, and we’re starting to see how toxic a mono’s relationship with a probe can get.
  • Worst moment: The excessive flashbacks are unnecessary and I can follow the plot just fine without them. We literally just saw a flashback scene take place less than a minute ago. What’s the deal with these flashbacks? Are they stretching for time because they don’t have enough footage?
  • My thoughts: There was a moment when Yoo Han said something like “I wanted to show you a rainbow…” and I wished that actually happened, because it would’ve been so much cooler. 🌈 It’s nice that Yeon Woo got emotional over seeing a colour swatch and a prism on the wall, but they feel so small in scope? Color Rush could’ve made a bigger impact with something more visually striking. If not a rainbow, take him to see a sunset, or an art gallery, or even a cinema. Why are we not thinking bigger and exploring this wonderful narrative opportunity more?

Episode 4

Yoo Han shows Yeon Woo a spectacular view of the night city.

Yoo Han shows Yeon Woo an impressive view of the city landscape at night. Worried about his growing attachment to Yoo Han, Yeon Woo gets panicky around Yoo Han and even injures him in an accident. When Yeon Woo suddenly has a color rush, it triggers traumatic memories of his missing mom.

However, Yeon Woo passes out from the strain and doesn’t remember what happened. Later, Yoo Han and Yeon Woo have an emotional encounter in the rain, which leads to them confessing their feelings for each other.

  • Best moment: When Yeon Woo regained his consciousness and couldn’t remember what happened, he said something like: “The colours…I can’t see them.” There was something just so heartbreaking in his expression as he said that. Poor Yeon Woo. Bless his heart.
  • Worst moment: Sorry, I’m not that convinced about Yeon Woo developing feelings for Yoo Han. From what I’ve seen, Yeon Woo loves Yoo Han’s ability to make him see colours, but has no real feelings for Yoo Han as the actual person. It seems more as if Yeon Woo had mistaken his feelings of gratitude for romantic love.
  • My thoughts: Is it just me or do these guys spend more time in the nurse’s office than they do in the actual classroom? 😆 I actually think I liked the scene in the nurse’s office more than the big dramatic scene in the rain. The nurse’s office scene felt more of an intimate and tender moment between the couple.

Episode 5

Yeon Woo cries when he sees the colours in his mom's portrait for the first time.

Yoo Han takes Yeon Woo to see a stunning art exhibition specifically about colours. The two of them have an enjoyable time.

After the show, they go to Yeon Woo’s home, where he sees the colours in his mom’s portrait for the first time. The emotions overwhelm Yeon Woo and he begins to cry.

  • Best moment: The scene where Yeon Woo cries over his mom’s portrait was so good. Ever since they introduced the portrait in an earlier episode, I’ve been waiting for this moment to happen, knowing that it will be very emotionally powerful. This scene turned out to be even better than I anticipated, with the actor delivering a fantastic performance that really resonated with me.
  • Cute moment: When Yoo Han didn’t come to school for the day, Yeon Woo and his friends created a made-shift doll to trick the teacher into thinking Yoo Han was there. I mean, the doll looked nothing like him and was the size of a small child. 😆 But it was still a cute little scene that lightened the mood.
  • My thoughts: I loved the concept of the art exhibit show and it produced some really pretty visual effects. With that said, it was probably more exciting for Yeon Woo’s character to experience than for the viewers watching. To me, all I see is a bunch of flashing lights on the walls and floors, but I’m glad Yeon Woo had an enjoyable time. ✨

Episode 6

Yeon Woo cries when his aunt suggests that he should transfer schools to be away from Yoo Han.

When Yeon Woo’s aunt suddenly arrives home, Yoo Han introduces himself as just a friend from school. However, she figures out their real relationship and suggests that Yeon Woo should transfer schools. This provokes a strong reaction out of Yeon Woo, who vehemently refuses.

Later, Yeon Woo hears from his friends that Yoo Han might not return to school anyway, since he’s getting ready to debut as an idol. Yeon Woo’s mental health deteriorates, and in desperation, he hatches a sinister plot to kidnap Yoo Han for himself.

  • Best moment: Yeon Woo delivered another terrific performance during the confrontation with his aunt. This actor is so good at getting emotional and crying his puffy little eyes out. The way he cried was different from last episode, where he was just plain sad. This time, you can see visible signs of distress in his mannerisms, and you can tell he’s more mentally disturbed.
  • Worst moment: I know Yeon Woo isn’t in a mentally sound place, but the decision to kidnap Yon Hoo seems so extreme? Last episode, he was happily attending an art exhibition. And this episode, he’s devising some kind of human abduction scheme. It feels like his mental breakdown escalated so quickly, jumping from zero to a hundred in such a short time. I dunno if we got enough build-up to justify this level of batshit crazy so quickly.
  • My thoughts: The story took a sharp turn in this episode. There were subtle hints of Yeon Woo’s mental health deteriorating in the past, but they pounded hard on the accelerator and went straight to looneysville. I know it suck to lose colour in your vision again, but do you not think you’re overreacting a little? Still, I enjoy the intensity of Yeon Woo’s mental breakdown and I was excited to see where it would take us in the next episode.

Episode 7

Instead of trying to kidnap Yoo Han for himself, Yeon Woo decides to commit suicide instead.

Interested in learning more about his point of view, Yoo Han asks Yeon Woo about the shades of grey he sees. While Yoo Han picks up on some distress, he doesn’t understand how bad Yeon Woo’s mental health has deteriorated. At home, Yeon Woo doesn’t plan on kidnapping Yoo Han anymore. Instead, he ties a noose and hangs himself in a suicide attempt.

Fortunately, his aunt saves him just in time, but she insists on isolating Yeon Woo for his own safety. Yoo Han tracks him down anyway, and he convinces Yeon Woo to run away together in the middle of the night.

  • Heartbreaking moment: Oh my god, I can’t believe Yeon Woo went that far. I didn’t see his suicide attempt coming, but it seemed obvious in retrospect and it definitely made more sense than the kidnapping plot. While I don’t want his character to kill himself, I know he has suffered a lot and can understand the factors that drove him to this drastic decision. It’s not just about his colorblindness, but also the sense of abandonment, the loneliness, and the hopelessness all coming together to form a dangerous psychological reaction.
  • Worst moment: Don’t know if I’m on board with Yoo Han breaking Yeon Woo out of the treatment facility following his suicide attempt. It feels extremely reckless and irresponsible. I mean, there’s a right time and place for a whimsical midnight rendezvous, but it usually doesn’t happen right after someone tried to kill himself. Is Yoo Han really capable of taking care of Yeon Woo in his current fragile mental state? 🤷
  • My thoughts: A sad episode, and I’m still shaken at how close Yeon Woo came to killing himself. Honestly, I would’ve liked it if Color Rush spent a bit more time on his recovery process. The suicide is such a dramatic moment, and the aftermath deserved more focus instead of just rushing to the next adventure with Yoo Han. Still, the most important thing is that Yeon Woo is still alive and hopefully he’ll be in a better state of mind next episode. Stay strong, Yeon Woo! 😢

Episode 8

Yeon Woo and Yoo Han kiss for the first and only time in Color Rush.

After running away together, Yoo Han takes Yeon Woo to the beach, where they gaze at the colours of the ocean waves. Yeon Woo discovers that Yoo Han quit being an idol trainee and ran away from his powerful family. In an honest chat, they open up about their feelings.

Yoo Han confesses that he suffers from face blindness, so he can’t recognize what anybody looks like, but Yeon Woo is the only exception. Yeon Woo feels a lot more reassured, knowing that both of them must depend on each other in this relationship. They share a tender kiss.

  • Happy ending: The series ends happily, with their lives going back to an everyday normalcy. The final shot shows the boys skipping class, with their hands clasped as they run across the school hallway together. 👬
  • Best moment: I liked their final conversation together, followed by a sweet and tender kiss. This chat was the first time we learned anything substantial about Yoo Han’s character, but sadly it came at the end of the series. His facial blindness condition seems like a convenient way to wrap up the plot happily, but I’ll take a feel-good happy ending over a sad and messy one.
  • Worst moment: At the beach, Yoo Han was just droning on and on about all these different colours. This is a recurring trend, and he has been reciting a lot of colours in the past few episodes. The dialogue often consists of Yoo Han listing out names of colours with some useless trivia fact about their background. This was cute the first time he did it, but it got less and less interesting when that’s all he ever talked about. Dude, I get it, you memorized the encyclopedia passages about different colours. Can we change the topic please?
  • My thoughts: This ending was fine on its own, but it felt a little unsatisfying as a series finale. Color Rush didn’t resolve the plot with Yeon Woo’s missing mom, barely touched upon Yoo Han’s sudden character development, and there’s so much other potential storylines they could’ve done with Yeon Woo. As soon as I finished this episode, the first thing I did was look up whether there’s a planned sequel (there isn’t) because the story feels unresolved in its current state.
  • Final thoughts: Despite a few flaws, Color Rush was a strong BL drama with some emotionally powerful themes and moments. I want to watch this story continue with a sequel. Hopefully, Yeon Woo continues to find happiness in his life, with or without colour, because his character is precious and must be protected at all costs.

  1. I was also bothered by the rushed ending and the total abandonment of the search for Yeon Woo’s mother, but I guess that’s par for the course for these too-short Korean BL series. On the other hand, I was captivated by Hyunjun Hur’s performance as Yoo Han. I had no idea that he was actually a famous K-Pop idol in real life, who was forced to retire from popular group The Boyz due to a medical condition. I’m really hoping to see him in more dramas soon.

  2. I SAW ON INSTAGRAM A FEW DAYS AGO THAT THERE’S GONNA BE A SEASON 2

    WE MIGHT GET TO KNOW MORE ABOUT YEON WOO’S MUM’S MYSTERY!! AAA

    and yes i agree, Color Rush is such a beautiful bl kdrama and the storyline is unique and interesting.
