"I will serve you wholeheartedly to ensure your complete satisfaction." "Please feel free to ask me for anything, whether it's housework or something more intimate." These words made housekeeper Reiko Sawamura a popular sensation. Her service goes far beyond mere housekeeping duties—she is known for willingly providing sexual services as a wife substitute, drawing widespread attention. Even her dispatch agency is amazed by her popularity; despite setting her fees unusually high, client requests for her continue to rise. The reason lies in her meticulous attitude and exceptional flexibility in meeting clients' needs. Today, assigned to a single father's household, she arrives as usual with a cool, serious expression, deeply committed to her "mission of service."
