I love the concept of the mono and probe, with the mono being colorblind until they meet their probe who lets them see color. Lots of potential for relationships which the drama did well with at times. I was hooked on the first episode and was pleasantly surprised by how good the actor for the main character Yeon Woo is. His acting feels natural in even serious moments. However the same can't really be said of of the actor for his love interest, Yoo Han. There's something about the way he talks that's too soft/monotone, and his emotions don't come across that well. Their chemistry is fine for the most part, except that kiss near the end lol...it looked super fake. There are other parts that make me laugh out loud, like when Yeon Woo sees color the visual effects are pretty cringe.

I thought the two guy friends in their class were cute, I wish they had more screentime but they just disappeared after like the first two episodes. Usually I get annoyed by the MC's friends but they were fun.

Storyline is good but chonky at times. Like it feels like there's a gap in between scenes or suddenly the main characters are really close for no reason. And at the end it reveals that Yoo Han has face blindness, which I feel like is a big deal too and could've been used for the plot but he just casually revealed it like wth?? I want to know more about Yeon Woo's mom and her disappearance. I'm looking forward to watching the second season, thought I wonder how it will be with a new actor for Yoo Han's character.
