JUY-365 From 13:00 to 17:00 on weekdays, I turn from my wife into a woman… YamaGishi Kotone.

Kotone lives a boring married life with her taciturn husband. A friend of hers recommended her dating site, which she initially despised, but with her sex life with her husband cooling down, she reluctantly started. However, Kotone, who was afraid to meet a man who was a year older than her, brought her to her meeting place, but she returned home. A few days later, a real estate agent came to Kotone's house, which was sold due to her husband's transfer. That man is the man Kotone had exchanged with on her dating site.
