Beautifully written drama. For someone who is not really craving for so called common romance, I like how the production team executes the romance part if this drama. It's not overdone, adequate. Ji Bai always have his own way expressing his interest towards Xuxu, vice versa. As for the crime parts, it is the emphasis of the drama. This drama requires brain and focus for you to keep understanding the whole situation. They have domino effect from one case to another. Ji Bai and Xuxu are just human, they sometimes did it wrong, they accepted it and move on. That's the most important part about the investigation side of this drama that I like. Each characters complete the other. Music and cinematography are great. Not only fair enough, but they really put extra attentions to these factors. I love the OSTs, background music and cinematography which helps me understand more about the scene. Definitely the best Chinese drama I have ever watched so far.
