This drama was not on my radar at all since I haven't watched a good Chinese crime drama in a long time. However, I heard some good things online so I gave this a try. The first couple of episodes do pull you in right away although the pacing could sometimes make you feel a bit tired. However, the main and supporting characters are introduced nicely and you get attached to them early in the drama because of the relationships on screen. These supporting characters are also a great source of comic relief to lighten up the mood. My favorites would be Wei and his 4 buddies in the station. The acting was also very great- from the entire cast. There wasn't only one person carrying the drama, which is what I hate.

As for the crime and the main case, I was immediately intrigued by the case. I am a big fan of these serial killer cases in dramas and this one was quite different although also a bit cliche. I liked how the drama slowly revealed more information and narrowed down the suspects in each episode. The final reveal at the end was not completely unexpected but it did surprise me how we finally reached that conclusion. I wish that there was more of an explanation of the killer's motive and M.O. but it is true that there are cases in real life that do not get everything tied up neatly. It was also a neat touch that the Western serial killers and criminal psychology were mentioned throughout the investigation. The process of investigating the entire case was also done well and realistically. The flashbacks were helpful and not too abrupt or confusing.

Would recommend it for crime lovers as it has a solid storyline and superb acting!
