I enjoyed this drama a little too much, not going to lie. The drama seems like your typical undercover dogs team with everyone playing their own roles, however, the team dynamic is truly so strong. They have disputes and it doesn't seem to end till the last moment, however, the insane character development from lack of trust and despise to love and family is most worth the watch. I admit that I chose to watch this drama because Woo DoHwan was in it, knowing how great and charismatic of an actor he is, however, the rest of the casting was equally as strong. The minimal romance scenes definitely leaves the audience craving for more, however, we're reminded once again that it's a thriller/mystery/action, not necessarily a romance drama. Therefore, I give the drama a solid 9/10.
