Title: Killing Stalking
Yoon Bum is a loner, but he doesn't want to be. Bum longs for companionship, but not just with anyone. He longs for no one other than Oh Sangwoo. Bum has been quietly stalking Sangwoo since meeting him during conscription after Sangwoo rescued him from an assault by his platoon leader. After figuring out where he lives, Bum discovers the numbers of Sangwoo's door lock and lists out every possible combination, which he decides to try so he can gain access to Sangwoo's house. Unfortunately, at the end of the list, a cop car pulls up and begins questioning why he is there. Bum is in a panic but is able to say he's Sangwoo's cousin before getting the code right and slipping inside.
While Bum sees this as a victory, he doesn't realize that the cops he spoke to know Sangwoo, and they end up telling him about the run-in with his “cousin,” prompting him to return home while Bum is lurking about. But having a stranger in his home isn't the main reason Sangwoo is in a rush to get back. While Bum is snooping about, he discovers a basement door in the floor with a lock on it. Once he opens it and heads down, Bum discovers a woman, bound and beaten. Bum tries to help her, but before he can get her free, Sangwoo finds him, knocking Bum out with a baseball bat.
Bum is now Sangwoo's newest victim. Can Bum survive this encounter? But more importantly, can he make Sangwoo love him as much as he loves him?
