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.
