服完兵役的高龄大学生恩植（任昌丁饰）就读于法律系，校园里满是对性充满好奇的年轻男女。可惜外表憨直的他没有什么女人缘，脑筋也是不大好使。一次偶然机会，恩植认识了学校健身俱乐部的头牌队员、校花级美女银孝（河智苑饰），他立马被对方的美貌性感吸引。恩植想尽办法接进银孝，博取好感，却都以失败告终，甚至引发许多误会，比如在公车上，他被银孝当成色狼一脚踢中要害。 　　后来，银孝迷住了有钱的花花公子相旭（郑敏饰），甚至怀了孕，但最终被抛弃，伤心绝望。与此同时，恩植和银孝之间产关系有了微妙变化。At Sunjong University, a few students are serious, including Eun-hyo, who works hard at aerobics in hopes of doing well in a national competition. Most students goof off: drinking, partying, and focusing on sex. Eun-shik, a law student who's been in the military, is older but socially inept. He likes Eun-hyo; even though his earnest and simple side appeals to her, his juvenile excesses make him irrelevant when Sung-ok, a good-looking rich kid, charms Eun-hyo. They begin an affair, leaving Eun-shik on the sidelines. The national competition approaches and complications arise.
