I can't remember S1 anymore since it was so not memorable. S2 is an independent drama with all different characters.

Nothing about this drama is amazing but if you enjoy crime dramas, this is a decent watch. The cases are standard, but I like the pacing, about 4 episodes per mini case while there is one big case. You won't grow emotionally attached to the characters or cases, but the characters are likeable enough. ML cop & ML's sister are both interesting characters as well as the mysterious informant Bai Zhe. The best scenes are the interaction between the ML's sister and the mysterious Bai Zhe. I wished they had more screen time.

Mini cases:
1. Not very strong, I would've dropped it if there weren't a bigger mystery with Bai Zhe.
2. Standard but better than the first one.
3. Case of the upcoming actress. I liked the twists in this one, so far the strongest mini case.
4. School case, straight forward

What's not so great:
Young female cop acts too naive to be a cop.
Unplausible super cop speed on saving people...
Not the greatest sets/stunts, prob low budget
Shaky hand camara shots, really doesn't work
