Mitsumaru is a high school student leading a secretive double life as the creator of an erotic manga. To bring his work to life, he has drawn direct inspiration from his everyday surroundings, going so far as to use a fellow classmate as the primary model for his illustrations. Operating under the assumption that his provocative hobby will remain hidden, Mitsumaru carefully balances his ordinary academic routine with his clandestine artistic pursuits. However, his fragile sense of security shatters when Yuu, a dedicated member of the school’s disciplinary committee responsible for enforcing campus rules, uncovers the existence of the illicit manga. This unexpected discovery thrusts Mitsumaru into a precarious situation, as the very student tasked with upholding the school's strict moral code now holds the key to his secret. With Yuu aware of his controversial creations and their real-life muse, Mitsumaru faces a mounting dilemma that threatens to expose his hidden work and disrupt both his school life and his relationship with the unwitting classmate who inspired it.
