Tanaka Setsuko, living alone with her son, has a secret job that must not be known to others. She disguises her prostitution business under the name of a care helper. She discreetly distributes flyers around town and quickly responds when contacted. Setsuko's main clientele consists of people with physical disabilities, though occasionally she receives inquiries from able-bodied men. In such cases, the men are usually exceptionally enthusiastic, and Setsuko finds herself enjoying the work, forgetting her duties... Two other stories are included.
