Wife: Ichiko Aihara. Husband: Otoya Aihara. Married for seven years, they get along well, but sexless and without children, they agree to see other people. Otoya has an affair with Mitsuki, and Ichiko is aware of it. Looking at Otoya in a state of bliss with Mitsuki, Ichiko begins to change, too... Peko Watanabe tells a story of lies and truth—whether or not you ever want to get married, the real life of this thirty-something couple might give you some second thoughts about that institution we call marriage!
