Lim Chan-Yeong was often physically punished by his teachers as a student, causing him to believe that he was masochistic. At the academy where he works part-time, he meets Goo Dong-Ha, a teacher with massive masochistic tendencies. Due to a drunken encounter, Dong-Ha mistakes Chan-Yeong for a sadist and the two embark on a whirlwind BDSM adventure together.
