At last, Go Eun-woo begins his first post as a school health teacher. His job satisfaction? A perfect 100%. Stable work, sweet long vacations, and predictable hours. A “handsome, neatly dressed school nurse with a friendly smile.” Both fellow teachers and students alike look at Eun-woo with admiration. Well—everyone except one person. The ethics teacher Im Seok-joo, who seems like he’s straight out of the Joseon dynasty.

*“What exactly did you teach during sex-ed? Why are you handing out things like this (condoms)?”*
*“Did you not think parents would file complaints?”*
*“Sexual intercourse is a sacred act—where a man and woman, once married and truly in love, join to conceive life.”*

Preaching chastity until marriage, Im Seok-joo clashes head-on with Go Eun-woo, who believes in maximum desire and free sexual relationships. From start to finish, the two simply couldn’t see eye to eye. At least… not until the day Eun-woo caught Seok-joo masturbating in the bathroom.

*“Teacher, shall I give you a hand?”*
