Yuri counteracts her husband’s concerns with a loving kiss and heads to the alumni reunion. Among the classmates she reunites with after several years is Tatsuhiko, her ex-boyfriend. Unlike Yuri, who was an exemplary student, Tatsuhiko was more carefree and outgoing. Even today, as he drinks alcohol, he tries to touch Yuri playfully. Although she now has a husband whom she loves, Yuri worries about Tatsuhiko, who continues drinking without concern for the consequences. As Tatsuhiko keeps drinking without listening to Yuri’s advice, he begins to feel unwell. Yuri can’t leave Tatsuhiko alone and accompanies him to the bathroom, supporting him on her shoulder. However, as soon as they reach the bathroom, Tatsuhiko closes the door and begins to touch Yuri’s breasts. Tatsuhiko had been pretending to be drunk to take advantage of the opportunity to be alone with Yuri.
