The young wife's sexual desires need to be satisfied.

Eri and her husband live happily together except that her husband is always busy with work. One day, Yuka invited her to attend a class reunion. Yuka shared that her husband is also always busy with work and wanted Hamano's advice. They organized a party for three, but Yuka had to leave early, leaving the two of them alone in a room. Hamano had admired Eri since they were in school together but never had the chance. This was the best opportunity for him to prove his feelings. Due to the lack of intimacy with her husband, Eri gradually stopped refusing Hamano's advances.
