Wife Izumi is 31 years old. After living together, she married her husband, who already has a prior divorce and a child. Watching him regularly visit his child stirs complicated emotions inside her. Their marriage gradually grows cold, and their sex life comes to a complete halt. Filled with anxiety and desperation, the wife begins questioning whether she's lost her appeal as a woman or if her husband simply doesn't want to have children with her. The woman he once loved has a child, yet she, his current wife, still does not. Trapped in an unbearable dilemma, she lies to her husband and goes on a trip—where she experiences pleasure for the first time in six months, trembling with the ecstasy of being a woman once again.
