Little Detective

Anastasia Barnes just got her dream job as a detective. Her first case with her new partner, isn't as easy as she hoped. Her partner goes to the leader of one of the city's mafia, Bangtan. She automatically doesn't like the man they meet and doesn't want anything to do with him.
Kim Namjoon, or better known as RM, has been the leader of the mafia, Bangtan for years. Sometimes when the police has cases that have to do with the underground, he helps. So when he meets a new, young, pretty detective, something about her draws him to her.
