Shady until the very end. I can say nothing. This dorama is very good for me (well, I don't know how with the other who didn't like the genre). You'll try to guess the bad one and the motive. Hmm ... so far the bad one can be guessed easily, but at the first you (at least me) can't find the connection with the main story easily. The motive not too clear, and the closure is quite flat. Well, I love the clear ending after all (^_^;)

(Warning : bloody scene exist!)
