One day, Princess Alicia, who cross-dresses to attend the male only Magic Academy, realizes that the world she is currently in is the setting of the BL novel she was reading in her previous life.

Her purpose at the academy is to get married to one of the candidates her mother has prepared for her, so that she can avoid a political arranged marriage. However, all the candidates are members of the novel's protagonist's harem. Close to giving up hope, she's spotted by a man she'd never heard of... a new character in the story! The handsome summoner Lucius demands her hand, and before she knew it, Alicia was falling for him!
