Mrs. Cop 2 (2016)

Both dramas are revolving around cops finding a serial killer. Very good selection of actors and actresses. The Girl Who Sees Scents is comparatively much less violent than Mrs. Cops 2. It is funny how both dramas start off with a scene of the female main character helping cops to catch a criminal around the mall. More description can't be given without spoiling the stories. You just have to watch to find out!

Both dramas are similar as they have police detectives & their struggle to fight against crime
This drama is also gives the same vibes of police investigation, procedures & other circumstances they face against the powerful peoples

these 2 dramas have some similarities. the villain is a spoiled chaebol's son who's the president of a big company. they have issues with anger management and no matter how much evidence the cops have against them, they come clear due to their connections.
