You and your best friend Hoseok are in your first year of teaching at university. Today you lost a bet and he forced you to kiss any stranger. The man you kissed looked a little older than you, but you thought he was a student.

Already in class, Hoseok joked and laughed at you while you told how it all happened. "You just kissed him and ran away? seriously?" At that moment the teacher entered the classroom... and it was the man you kissed. Wait, is the man you kissed your new teacher?
