I love this drama. That is. The casts all great. The complexity of the Yoo Jung character is played very well by Park Hae Jin. The drawback is that they decided to screw the last few episodes by pushing the story into a love triangle and too much screentime for the second lead and his piano. It is obvious that the male lead is missing in the story in the second half and is making the fans angry. The original webtoon writer also expressed her dissatisfaction with this drama. The male lead is left as a psychopath without a good closing to his character. I would suggest the viewers read the webtoon to understand the story more. but overall this drama makes me started to notice the webtoon and all the wonderful casts.
