Yuko was troubled by her husband's behavior and confided in her best friend Nagisa. Yuko's husband's possessiveness was intense because of his love for her, and she had barely managed to get his permission to meet with Nagisa. Seeing Yuko's situation, Nagisa smirked, coming up with a plan. As Nagisa listened to Yuko's complaints, she urged her to drink more alcohol, enjoying a pleasant time together. That night, after Nagisa dropped off Yuko at home, she and Yuko's husband Shinji carried her to the bed. Concerned for Yuko, who was passed out drunk, Shinji was taken aback by an unexpected kiss from Nagisa, who looked at him with sultry eyes. Despite his surprise, they ended up having sex.
