If you are thinking about watching this, take note:

- this is not a drama with three seasons but one 36 episode drama split in three
- there are a lot of loop holes, you'll find yourself saying a lot of times "but..."
- the romance scenes are really good but sometimes scarce, you have to be interested in police drama too
- there are a lot of rapes and multiple rape scenes, beware if you are triggered by this
- you can buy iQIYI to watch this with high quality picture, but the subbing there is made by an AI and quite crappy. Take note that the police Cold Noodles is actually called Cold Face, and in the first season when they talk about the FL being "lu chi", it means she has a bad or no sense of direction at all.

If all this is fine for you, give this drama a chance! I myself found it entertaining and watched it in a few days, without getting bored.
