Sex Is Zero is a 2002 South Korean comedy film directed by Yoon Je-kyoon. The film follows the story of a group of university students and their erotic misadventures.
Eun-hyo, the protagonist, is portrayed as a serious student who is dedicated to her passion for aerobics. She is a member of the university's aerobics club and is training hard to compete in a national competition. Her hard work and passion for aerobics are put to the test when she starts to fall for Sung-ok, a wealthy and handsome student who is a bit of a party animal.
Eun-shik, a socially-awkward law student who has completed his military service, develops feelings for Eun-hyo; however, his juvenile and awkward ways make him less attractive to her. Despite Eun-shik's advances, Eun-hyo is drawn to Sung-ok's charm and good looks, and they begin an affair.
As the national aerobics competition approaches, Eun-hyo and Sung-ok's affair becomes complicated when Eun-shik begins to make a move for Eun-hyo's affections once more. Meanwhile, the other university students continue to pursue their own sexual interests, leading to a series of hilarious and chaotic mishaps.
Sex Is Zero is a raunchy, coming-of-age comedy that explores the themes of love, sex, and friendship. The film's explicit content and comedic approach made it a box-office hit in South Korea, and it spawned a sequel in 2007.
