Well what to say at the beginning I wasn't so excited about watching this drama, but while watching the first episode I became attached to it. It's just amazing, how the story is well written, the acting is so damn good, the actors have put a lot of efforts in it . What I didn’t like was that each time I get the feeling that I'm close to solve the case it gets more and more complicated, I mean come on guys why make it so complicated that’s what I thought at the beginning but then everything just fits perfectly in sync with the whole story to make it more tragedy, thrilling and mind blowing. The actors: Yook Sung Jae : the good police man, the charming, caring angel, and my god he is so cute. I loved him the way he acted is amazing to make you believe him and cheer for him. Shin Eun Gyeong : WOW just wow, I was taken back by her powerful acting, she is super amazing, and that character that gets you to be compassionate, sympathetic and for sure angry at her most of the time, how she got into the role to perfect the character like this is awesome. Choi Jae Woong : I must say that I loved his role; he got me confused all along the drama, trying to figure out if he is a bad guy or just a psycho. He really played it well as how can you love a killer & sympathize with him … he is soo good , just want to see him in more dramas he deserve it. Well done.
