A young man tries to make sense of his conflicting emotions concerning love and sex in this coming-of-age drama from South Korea. Ja Hyo (Kim Rae Weon) is a student in his last year at high school who attracts the eye of a girl named Ha Ra (Yun Ji Hye). Ha Ra throws herself at Ja Hyo, but he is unable to return her love after they've slept together. Ha Ra falls into a deep depression and commits suicide; shocked and saddened, Ja Hyo finds himself unable to commit to a relationship with a member of the opposite sex. He becomes involved with Nam Ok (Bae Doo na), an older woman working as a nurse, but while Ja Hyo isn't sure if he's ready for a long-term relationship, Nam Ok isn't about to let him get away from her. Meanwhile, Ja Hyo's best friend Su In (Kim Jeong Hyeon) has romantic problems of his own - he's fallen in love with his teacher, Jeong Hye (Jin Heui Kyeong).
