If you're a fan of crime dramas, this would be want which you should not miss :) It does not have that typical crime drama storyline where it usually revolves around a team of detectives solving cases after cases without any value in the story, so you'll have to watch till the end to catch what kind of message this drama is trying to put across. I like how the characters in this drama build up that relationship with each other despite being different from each other. I would say they casted the perfect team of actors to play the different characters. In this drama you'll definitely get to see Park Hae Jin portrays a different character from his usual ones :)
