This summer, Hosoda returned to his hometown. He is working as an office worker in Tokyo, but he is exhausted from failure. His family's guesthouse is currently run by a relative, and Natsu lives there. Although they are not related by blood, Hosoda has always been close to him as a relative, and while Natsu has been asking him about life in Tokyo, she asks him if she is attractive as a woman. Despite her cute appearance, Natsu has amazing wanking skills, and Hosoda succumbs to her seduction and molests him throughout his visit home.
