What I really liked about this drama is that every actor here acted very naturally and professional in their roles. The leads as well didn't do too much out of character, just nice for Shen Yi's slightly oddball yet mysterious personality pairing with Du Cheng's initial headstrong character. I'm really thankful this drama didn't portray criminals like they are psychopaths like some recent dramas of the same genre. I really appreciate that the scriptwriter kept criminals' behavior and motives realistic and logical which many dramas really lacked these days...

So for some parts I really didn't like is how they lack some realistic details when inspecting the crime sites... Such as the need for wearing gloves yet no SHOE COVERS when entering the victims' place... I was like "huh? seriously surely they must be kidding right..." A lot of the times, both the leads also didn't wear masks nor gloves when handling the dead bodies when the forensic was wearing it... I mean I kinda got distracted while being engrossed in the episode.

But overall this drama is one of the really good crime suspense production as compared to many released recently! Not mentioned I had quite a crushed on Shen Yi's charm that makes people open up to him and the desire to friends with such person XD Tan Jian Ci is really a rare actor that portrays his characters so well that made it charming and unique for every characters given the fact that he wasn't even professionally trained!
