It's been a while since I lived with my cameraman's father-in-law, but my naive daughter-in-law, Yuna, couldn't forgive her father-in-law's sexual harassment. One afternoon, Yuna, who had too much free time after finishing her housework, was frustrated with her frank husband, Seiichi, and she ended up masturbating. She takes advantage of no one to see her and exposes her dementia, but she happens to come home and her father-in-law films her the whole story. When Yuna finds out about it, she immediately imagines what will happen, and she is terrified.
