Comedic but more serious than its predecessor Wet Dreams, it follows four girls in high school as they become curious about sex and compete for the affection of their new teacher.

[1] The film, set in 1992, starts with a marriage ceremony of Sungeun's sister, and the high school girls envy the married couple and dreams of meeting their true love.

The girls' names are Sung-eun (Kang Eunbi), Soo-yeon (Jeon Hye-bin), who fights bullies, and Mi-sook (Park Seul-ki) and they are all disappointed about not being a popular girl like Baek-saemi, who is a celebrity.

Kang Bong-goo (Lee Ji-hoon), the new student teacher suffers from a problem where he farts when aroused.

Bong-goo's friend tries to examine if that is a real problem and asks him to watch the Jean Jacque Arnot film The Lover together, but the girls happen to be in the same theatre, that an R-rated film is being screened, to watch the movie, and Sung-eun falls in love with Bong-goo the next day in the classroom.
