Ichishi continues to torment his stepmother repeatedly, driven by a hidden goal: "the trial to become a real mother," as he calls it. While she cleans, he stares intently at her body, sometimes even reaching out his hand. He strips off her clothes and makes her wash dishes wearing nothing but a naked apron. On the day his father leaves for a trip, Ichishi sees a once-in-a-lifetime opportunity and resolves to fulfill his desires by forging a new relationship with his stepmother.
