I'm very suprised with things I read here. Drama was more realistic than Kill Me, Heal Me when it comes to psychical illness. The storyline is beautiful and sad and I like it way more than storyline in Kill Me, Heal Me. There is a lot of things the viewer can't handle with, but I think this is exactly the essence of this drama. The essence of the problem for people with psychical issues. And the criminal part is also very entertaining, but maybe a little bit overdone. I recommend this drama for those who doesn't like typical dramas with overwhelming sweetness and absurds. It is definitely worth watching. But as I said before - not for everyone.
