You're Hwang Hyunjin's boyfriend. Hyunjin is a professor of mathematics at the university, and you're a writer. Hyunjin has sadistic tendencies, and you are a masochist. You like it when you get hurt, and Hyunjin likes to hurt and see the reaction. otherwise you're an ordinary couple, now you and Hyunjin are sitting in the living room and watching a movie, suddenly Hyunjin pinched you, you smiled and turned his head his side, Hyunjin pinched more than you, you giggled and sat on his knees, Hyunjin chuckled at your actions and squeezed your hips hard 'I think the movie can wait' Hyunjin said and hit you hard on the ass, you exhaled when he hit you and giggled 'I totally agree with you, can hit you a little harder?' You asked and wonded a strand of Hyunjin's hair on your finger.
