As someone who loves crime shows without romance, this is perfect for me. I really enjoyed watching this show. I couldn't wait to watch the next episode after I finish the airing one.

PROS
1. Character Development - Through the course of the show, we can see how Wenjie's character grows as he experiences different things.

2. Acting - All the actors did a brilliant job portraying their characters.

3. The mysteries - They crimes and investigations were gripping and fast-paced. It was not dragged out.

4. The crimes and character development is the main focus of show. There is virtually no romance, except of hinted lines.

5. The contrast of characters - The characters are different in their morals, decisions, and thoughts. This made the show more contrasting and interesting. It was much better than having all the people on one side think similarly.

Cons

The only thing I disliked about this is predictability of the villain. It was really obvious who the villain was. It was weird that the ultra-smart and attentive Wenjie didn't notice anything or get suspicious.
