I'm not really into Police murder serial cases. This was good because it didn't really show bodies. I was able to tolerate most of it. I love the actor Yeo Jin Goo in anything he does, he is such a great actor so when I see that he is in the main lead, I know the character he portrays will be believable. Shin Ha Kyun, I have seen him in many dramas and I love him. The storyline was good. The visual was not bloody... bloody! Well, only hands here and there... not something you would have a nightmare about. No romance is this... mmm not used to that. The ending I love!
