In her fifth year of marriage, Ayumi is a virtuous and beautiful wife who aches at the sight of her husband's small factory struggling financially. As month-end approaches, her diligent husband constantly chases funding, returning home utterly exhausted. Though a homemaker, Ayumi secretly wishes to contribute to the household by finding work. One day, while returning from shopping, a black luxury car pulls up beside her. Out steps a gentleman who greets her with, "Long time no see!" It's Yuuji, her senior from a university club. He now owns several soaplands in a nearby red-light district and lives a wealthy life. Seeing him stirs deep emotions within Ayumi.
