I love this movie but the first movie totally amaze me. Waiting for part 3. (^^, 

Three years later, Eun-Sik (Im Chang-Jung) doesn't have much like with girls. He's dating Kyung-Ah (Song Ji-Hyo) from the swim team, but he hasn't got past a kiss. Meanwhile, Sung-Guk (Choi Sung-Guk), leads the K-1 club. The club also happens to share their building with the swimming club. Sung-Guk, is a self-professed expert on sex and relationships and he attempts to help Eun-Sik get past the kiss stage.
