first of all this drama was nice till ep.13 the story was about a man who had a (Dissociative identity disorder) a critical case and his shrink couldn't heal him for years then suddenly the writer decided to make a circus girl who knew nothing about Psychiatry or even a critical case like (Dissociative identity disorder) to manage with this serious case as if she was a shrink and above all of that she treated him as if he was two persons not a sick one she teased me soooooo i felt that the story underestimated my mind really i hated it my opinion it 's really really overrated i liked sung joon role so much he is a brilliant actor
