Sex Is Zero

After serving a two-year mandatory military service, Eun-shik is transferred to the National University, where he plans to major in Law.

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.

Although Eun-hyo sympathizes with Eun-shik's one-sided love, she eventually picks the most handsome student in college, Sang-ok.

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.
