Started interesting until they paired jung oh and sang soo. I see no chemistry of them but just a good friend. They just pushed it because they are main lead. For me, jung oh and officer Choi is a better and interesting pair. This just ruined the whole story for me. I still give 7 because most actors are amazing and the story interesting though lacking in some parts. For sang soo, i don't like his character potrayed by Leekwangsoo. Sulking a lot in an annoying way. I can stand watching him until he started dating jung oh while the other man (choi) just slowly dissappear from screen and i stop there. Sorry , maybe just me but this kind of love line annoyed me.
