High school student Yoshiki Maeda begins a new academic year at the all-boys Baraman High School. On the first day, Yoshiki reunites with his childhood friend, Takuya Saotome, and encounters his eccentric and theatrical homeroom teacher, Teruhiko Saionji. Yoshiki's younger sister, Yuu, is well-acquainted with many of these handsome boys and appears to enjoy teasing her older brother about them. Yoshiki quickly uncovers a cast of stereotypical romance characters and finds himself forced to cope with their blatantly absurd and nonsensical boys' love antics.
