The wife works overtime with her boss at the hotel to earn extra money to support her husband.

Aoi, the husband who was fired from his job and is struggling in life, went to Ozawa's company for an interview. Ozawa offered Aoi a position as a secretary even though it was an office recruitment. The salary doubled, but it came with a mistress contract. Although they were considered lovers, they did not have a physical relationship and only kissed. Aoi accepted these terms for the sake of her life. However, kissing Ozawa felt like mating between a penis and a vagina, and Aoi, who was experiencing pleasant sensations, broke her promise and requested to have a physical relationship with Ozawa.
