Wow, the drama is so messed up yet so good, they both find happiness from each other even if it's not real. Their relationshipis is something society would hate but through the way they meet they really got to know each other. The whole time watching i was wondering why he never took of his mask, but at the end he did. The the ending was something, it hit me really bad i was crying so much at the fact onii san died. He's such a angel from saving her from everybody . This drama has so many plot twists it played with my feeling it also is so dark.
