I like how the main leads (Allen Ren and Seven Tan) were able to portray their emotions using their eyes. The supporting cast also made some scenes so funny and sad. I finished watching the drama but I can't get it out of my head. From two officials that always butt heads to working together towards a common goal and then helping each other and finally falling for one another, this is the best chinese drama I have seen.
I also like the investigative method and reasoning that highlighted the crime solving, the romance that was gradual and touching, the action scene choreography which showed the other actors and actresses face and the properly timed scenes with background song plus the independent women characters and the realization that you can choose how to live your life instead of going with the flow.
