Rinta, who moved to the city from the countryside and enrolled in a university in the heart of the city, meets Fumi-san, rumored to be the most beautiful girl on campus, in the literature club he joined. After attending a drinking party together, he ends up walking her home. He safely escorts her to her house and is about to head back when suddenly Fumi-san transforms and forcefully invites him to her bed!? I wonder how long you can keep being a good person, Rinta-kun? Fumi-san pushes Rinta to his limits, testing his self-control until it shatters. Thus begins a forbidden university life filled with temptation.
