Married for almost a decade, a couple with a son have their life thrown for a loop when the wife Isoko comes across a photo of her university professor husband Asakichi with a younger woman named Terue, alongside a gift and a letter. When the husband is confronted he admits to merely loving his wife non-romantically, prompting her to take her son and leave the house. While she returns to her previous job and is staying at the company's dormitory, her husband is being visited by the other woman, who wants to tend to him, and his students.
