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 man and woman alone in a room. Hamano had admired Eri since they studied together but never had the chance. This was the best opportunity for him to prove his feelings. Due to the lack of intimacy in her marriage, Eri gradually stopped refusing Hamano's advances.
