In her fifth year of marriage, housewife Shiori lived a peaceful life with her kind and hardworking salaryman husband. He was always considerate toward others and often relied upon by friends and acquaintances. One day, he brought home an old friend he had coincidentally reunited with after work. The man introduced himself as Noguchi, roughly the same age as her husband, currently unemployed and seeking work. Upon learning he had no home and was living alone, Shiori felt uneasy but had no choice but to support her husband's decision.
