Great story about people who suffered Mental disorder. Cast are amazing. It has the best OST and most of the songs are in English. The OST is the one I will save and will listen to when I'm having a long drive. Drama made us learn how to deal people with disorder. Jo In Sung acting is perfect and I'm surprised about D.O he is really good too. The romance is a bonus. I Will say this drama is the best No Hee Kyung's drama. Well-written script and she did a lot of research to make this drama believable and worth watching. Recommended Jo In Sung drama. The chemistry of the whole cast os great.
