<The presence of a married woman at the part-time job who seems within reach...> A man whose daily routine was to listen to the complaints of a part-time housewife was alone with the married woman Mina as usual. And as always, nothing happened... but today was different... Before they knew it, they had sex and were in an affair. From the day the wife's dormant sexual desire, which she had been restraining, was awakened, the two of them indulged in naughty things whenever they had free time. They had sex every day, even though they both felt a sense of immorality.
