Kaoru's new-found popularity among female classmates after his performance with Sentaro causes Ritsuko to question her true feelings for him. Yurika comes upon Junichi and follows him back to his new apartment where she confronts him about a kiss they had shared at the record shop. Junichi unsuccessfully attempts to scare her away and her stubbornness, even going so far as to cut her hair to prove her point, forces Junichi to remember his regrets during his time as a member of the Japanese Communist Party in college. At school, Sentaro overhears students talking about Yurika's change in behavior and appearance and assumes that Junichi had done something to her. He goes to Junichi's apartment to confront him only to discover Yurika there with him. Sentaro tells Kaoru about what he had seen but Kaoru scolds him for not being aware that there was already someone in love with him. Sentaro soon realizes that the person Kaoru had been talking about was Ritsuko.
