The story is poignant and yet so beautiful. Friendship and brotherhood formed by the 2 main lead in an unconventional place and time. This is rather very painful to watch becoz of how they were treated inside the mental institution, I bet this things definitely happening in some places. This is an eye-opener indeed.

Acting wise, of course, there's no question if it's Yeo jin-goo and Lee Min ki, both are crème de la crème of kdrama world. The supporting casts did an excellet job as well. The story is a roller coaster ride, so be prepared.
