Well unfortunately you will not find anything better than Reset. If you check my dramalist you can see that Reset is the only drama I ever gave a 10 rating. It's just really satisfying to watch, great writing, pacing is just right and relationship development between the characters are just so good and realistic. It doesn't try to be anything grand or new but it is simply perfectly executed and I can't really find anything that I don't like about it.
Second best cdrama thriller/police drama is Under The Skin imo. Lu Yan Qi is my favorite "support" actress, I think she has the looks to play main roles idk why she never does that basically.
After you watch these better lower your expectation. Let me know if anyone find anything better.
