While hospitalized, an AV actor suffering from a knee injury that has cut off his income receives a job offer. When he asks if there are any cute girls he might meet at the hospital, he's told about a charming female physical therapist who's been helping with his rehab. Hearing this, he decides to pursue sex with her. After about a month of hospitalization, his knee still hurts but his dick remains strong. During rehab sessions, when her breasts accidentally brush against him, he gets uncontrollably erect. His first chance comes with Miss Shiina—a beautiful, fair-skinned woman with short hair. He approaches her, sensing she might give in, but aborts the attempt when his roommate returns. Next, Miss Noda, a married woman, becomes his therapist. Left alone with her in the rehab room, he desperately seduces her and forcefully kisses her, though he winces in pain from his knee. Feeling sorry for him, she eventually agrees to have sex. On his final day in the hospital, he lavishes praise on Miss Shiina and finally sleeps with her. The story unfolds through unexpected relationships sparked by chance encounters and intimate rehab sessions within the hospital.
