I was utterly surprised how good this movie turned out. I saw Lee Dong Wook was in it and thought why not. Man when I tell you he is the best villain I've seen in a long time. He was manipulative, conniving, endearing, likable, crazy, etc. I absolutely loved him. Si Won or whatever his name was absolutely adorable. He looked so innocent in the beginning and you could slowly see his mental decline as he fell into darkness. Ending was great, they didn't drag it out too long.

I WOULD HIGHLY RECOMMEND WATCHING THIS.
