The film opens on nineteen-year-old Jin-goo, a college repeater consumed by the lust of adolescence. He frequently fantasizes about his pretty, new English tutor. One day, however, his private moment is discovered, leading to immense awkwardness between the two. But rather than ending the lessons, this embarrassing incident becomes a bizarre catalyst. The tutor takes advantage of the situation, and she begins to teach Jin-goo about sex, not just English. Their relationship quickly spirals into an uncontrollable, passionate romance. As quickly as it began, it ends when she abruptly quits tutoring and leaves to get married, leaving Jin-goo emotionally scarred and accustomed to meaningless, thoughtless sex.
