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 about how her husband is always busy with work and wanted Hamano's advice. They held a party for three people, but Yuka had to go home first, leaving the man and woman in a room. Hamano is someone who has admired Eri since they were studying together but never had the chance. This is the best opportunity for him to prove his feelings. Due to the lack of marital relations, Eri gradually stopped denying it to Hamano.
