light-headed detective drama with a little bit of romance and bromance

Most of the time I personally don't watch Romance drama but i started watching this drama since detective mafia/policemen drama is my favourite genre and along with bromance is a bonus.I am truly amazed by female lead's acting skill.I legidly cried everytime there was an emotional scene. I really enjoyed this drama. Every case was unique so I didn't feel bored watching not even for a moment. I was enjoying it so much that i was watching it in a slow pace since I didn't want this drama to end.
This is a must watch if u love detective drama.
