Kimito Kagurazaka is a commoner with a fetish for men's muscles—or at least that's the lie he must keep telling if he wants to keep himself out of trouble at the elite all-girls school, Seikain Academy. Kidnapped by the school under the assumption that he prefers men, Kimito is made to be their "commoner sample," exposing the girls to both commoner and man so that the transition to the world after school is not jarring. Threatened with castration should his sexual preferences not match the school's assumptions, Kimito keeps up the facade to protect his manhood. But there are eccentric individuals around every corner who begin to make Kimito's life even more difficult. Among them are Aika Tenkuubashi, a social outcast who blurts out whatever comes to mind; Hakua Shiodome, a young genius; Karen Jinryou, the daughter of samurai who is obsessed with defeating Kimito; and Reiko Arisugawa, the perfect student who has delusions of marrying Kimito. Along with the commoner himself, these four girls make up the Commoner Club, which attempts to teach the girls more about life outside the school, while Kimito gradually learns about the odd girls surrounding him.

Rei Oohashi is a burned-out office worker by day but otome game heroine Rae Taylor by night. After her long workdays, Rei immerses herself in the world of her favorite dating sim, Revolution, as a student at Bauer Kingdom's prestigious Royal Academy. Instead of focusing on the male love interests, Rei obsesses over the romantic rival: the game's villainess, Claire François. One evening, however, Rei's exhaustion catches up with her and she passes away. When Rei opens her eyes again, she finds herself reincarnated as Rae and in the presence of her beloved Claire. Given this miraculous opportunity, she wastes no time declaring her love for the golden-haired villainess and her endearing attempts at bullying. Winning Claire's heart is no easy feat, especially as the game persistently throws the three male leads at Rae—but she has no intention of allowing the dating sim logic to come between her and the one she truly loves.
