While on a solo camping trip, Taichi witnesses a murder, and is taken prisoner by the assailant. Locked up in a strange room with his hands and feet bound, Taichi wonders if his life is about to end when the murderer suddenly licks his ear! The masked man then plants himself in a chair and starts staring at him. Taichi's puzzled, wondering what's happening, when his captor says he's fallen for him. And Taichi had thought the guy wanted to kill him! In a desperate attempt to get away, he tells the murderer that the feeling is mutual. The next thing he knows, the guy suddenly gets physical! It should have hurt, but it's getting better and better... as the Kansai native and the masked murderer begin a strange life together!
