One day, a cash-on-delivery package arrives at Rin's house. But without her on hand, she temporarily borrows her cash from her father-in-law's purse, which she happens to leave behind. Her father-in-law, who witnessed her, questioned her. "Rin" makes excuses, but her father-in-law refuses to believe her. And he semi-forcefully strips Rin completely naked and does everything she can to overpower her.
