Yui worries, "I feel like I'm being peeped at in an obscene act." She actually had her Yui fucked by her husband's father on a daily basis, and she thought it was because of that. However, one day, when she was examined by a psychiatrist, she was diagnosed with obsessive-compulsive disorder and "accepting everything is the first step to improvement." , but no improvement was seen. When she received her medical treatment again, her doctor told her, "The next time she's obsessed, invite someone who's peeking. Then her disease will show up." . When she comes home, Yui does provocative masturbation to those who feel her gaze, as her doctor said.
