The plot follows the story of college student Eun-shik and his efforts to impress a Junior, Eun-hyo. Eun-shik has a habit of finding himself in awkward situations that often embarrass him and sabotage his attempts to impress Eun-hyo. After serving a two-year mandatory military service, Eun-shik is transferred to the National University, where he plans to major in Law. He stays with 3 other roommates; most of them are typical college freshmen who are equally perverted. Eun-hyo, an aspiring national aerobic athlete, first notices Eun-shik, who is somewhat of an eccentric, in the college canteen while he stared at her tightly clasped thighs protruding from her lower mini-skirt. With a mischievous intentions, she spreads her legs tauntingly, and a glimpse of her white undergarments catches Eun-shik by surprise. Afterwards, their awkward encounters follow. Although Eun-hyo sympathizes with Eun-shik's one-sided love, she eventually picks the most handsome student in college, Sang-ok. While two-timing with another aerobic athlete, Sang-ok spends one night with Eun-hyo, which leads to an accidental pregnancy. Due to his wealthy and spoiled upbringing, he offers her money for an abortion emotionlessly. Insulted by his actions and his lack of responsibility, Eun-hyo runs away and tries to abort by herself. The doctor from clinic requires someone to accompany her during the procedure and recovery. At a loss of who to confide in, she turns to Eun-shik for help, who is initially illusioned that they are going out on a date. Due to his kind demeanor, he helps her with everything after her procedure; he aids her during her post-operational fever, cooks her meals, and keeps her company. He even tries to entertain her after her recent breakup with Sang-ok. Finally, on the day of national aerobic competition, Eun-hyo manages to come onstage at the last minute and performs with all her might. After the competition, she gives in to the looming sadness from her abortion and breakup. She goes to the restroom, cries, and bleeds from her womb as an aftereffect from her abortion operation. Eun-shik notices her missing and sends her to the hospital after discovering her in the restroom. Out of frustration and deep-seated hatred of Sang-ok, he searches for Sang-ok. He finds Sang-ok enjoying himself after the competition. He tells Sang-ok about Eun-hyo's recent tragedy and punches him. At the end of the movie, Eun-hyo is discharged from the hospital and asks Eun-shik if his feelings still remain the same.
