One year after remarrying, Kaori has been tormented daily by Akira and Ryo, her husband's sons. Her own son, Takeshi, witnesses his mother's suffering and blames himself. When Kaori tries to confront Akira, he forcefully overpowers her, and she eventually gives in to him. Since then, ashamed of her actions, Kaori copes by masturbating every night to soothe her pain. Takeshi sees everything and, crushed by his own helplessness, begins to feel even deeper affection for his mother. Finally, Kaori bares herself completely and opens her body to her son. For her, Takeshi becomes her only salvation—and a new hope.
