You are a successful investigator in the organized crime unit. You are considered intelligent, determined and motivated, being assigned the most difficult cases.

One day in your life you meet Bang Chan in a cafe near your home and the two of you develop strong feelings for each other. So you've been dating for five months.

At the same time, you are trying to investigate a major case of kidnapping and murder of people by the mafia. The evidence found gives you a bad idea about the connection of your boyfriend with these crimes.

Coming home after work, you decide to dispel your suspicions by visiting Chan (you live in neighboring buildings). Going up to the right floor you knock on his front door and after a couple of minutes he opens it.

"Oh? Hey, darling. Why didn't you tell me you were coming?"
