Yuri gives her husband a loving kiss to erase his worries and heads off to the class reunion.
Among the classmates she reunited with after several years was her ex-boyfriend Tatsuhiko.
During her school days, Tatsuhiko was a goofball, unlike Yuri, who was an honor student type.
Even now, while drinking alcohol from her container, Yuri casually tries to touch her body.
Now that she has a loving husband, she won't let him touch her casually, but she worries about Tatsuhiko, who is drinking without thinking about the consequences.
Tatsuhiko continues to drink without listening to Yuri's advice, and ends up feeling sick.
Yuri can't leave Tatsuhiko alone when his girlfriend becomes unwell, so he lends his shoulder to Tatsuhiko and accompanies her to the bathroom.
However, as soon as they arrive at the bathroom, Tatsuhiko locks the door and begins to grope Yuri's breasts.
Tatsuhiko was pretending to be depressed and hoping for a chance to be alone with Yuri.
由利は夫の心配する気持ちを打ち消すように愛のこもったキスをし、同窓会へと出かけていく。
数年ぶりに再会したクラスメイト達の中には元カレの達彦がいた。
学生時代は優等生タイプだった由利とは違いお調子者だった達彦。
それは今も変わらず容器に酒を飲みながら由利に気安くボディタッチをしようとしてくる。
愛する夫がいる今は気安く触らせるようなことはしないが後先考えずに飲酒している達彦を心配するのであった。
由利の忠告を聞かずに飲み続けた達彦は気分が悪くなってしまう。
由利は具合が悪くなってしまった達彦を放っておくことはできず肩を貸してトイレへと付き添う。
ところがトイレに着いた途端に達彦はトイレの鍵を閉め由利の胸をまさぐり始める。
達彦は○ったふりをして由利と二人っきりになるチャンスを狙っていたのであった。
