Yuzu Aihara's mother remarried over the summer of her freshman year of high school, causing her to relocate to a new school. This uncomfortable occasion is just another chance for a trendy socialite like Yuzu to make new acquaintances, fall in love, and eventually experience a first kiss. Unfortunately, Yuzu's goals and fashion sense do not fit in with her new ultrastrict, all-girls school, which is full of submissive shut-ins and overachieving grade-skippers. Her ostentatious presence attracts the attention of Mei Aihara, the attractive and intimidating student council president, who instantly begins sensually caressing Yuzu's body in an attempt to get her smartphone.
