I rarely got the feeling of excitement just by watching the first episode. You may get a lot of questions at first but for the following episodes they will answer them little by little! We have different taste in K-drama but if you're going to watch this, you have to ready yourself to feel it, understand and have an open mind. The thing that I really like is on how this drama shows characters' feelings and emotions in different form so the viewers will understand the depth of it and mental illness. The main characters have a strong chemistry! I've also read comments on different flat forms and they are mostly positive! I can't wait to finish this faster! It's highly recommended!
