Kotone, who lives a quiet and dull life with her reticent husband, was recommended a dating site by a friend. Initially dismissive, she decided to try it out cautiously due to her cold marital sex life. However, Kotone became scared when she was to meet a man much older than her and ended up returning home without meeting him. A few days later, with her husband's transfer, she had to sell their house. The real estate agent who came to her home was the man she had been communicating with on the dating site.
