Tokyo. Mihoko and Toichi Nakagawa's ten year marriage is crumbling out of inertia. Each knows the other isn't happy, they themselves aren't happy, but they don't talk about their problems with each other, each festering in their unhappiness largely so that they will not show especially to their three boarders their problems. Mihiko in particular, old fashioned in her outlook, does not see divorce as an option, that move which would be a stigma she could not tolerate. Both are seemingly oblivious to the fact that others around them are facing similar if not worse situations, and that they themselves are largely the cause of their unhappiness. Things for their marriage get worse when Toichi starts to fall for his work colleague, widowed Fusako Sagara, who returns his affections.—Huggo

Ten years into a marriage, the wife is disappointed by the husband's lack of financial success, meaning she has to work and can't treat herself and the husband finds the wife slovenly and mean-spirited: she neither cooks not cleans particularly well and is generally disagreeable. In turn, he alternately ignores her and treats her as a servant. Neither is particularly happy, not helped by their unsatisfactory lodgers. The husband is easily seduced by an ex-colleague, a widow with a small child who needs some security, and considers leaving his wife. She fights back, writing to and visiting the mistress to demand she leaves her husband alone. He consults his friends, she her relatives. Around them, marriages are ending in fights and suicides but in this case, the mistress gives up the stressful fight, leaving the couple together again, no happier than before.
