It's quiet and unfriendly, but I got married because I was attracted to the seriousness of people, but ... I'm not bad at all, but Eri sometimes felt a crevice in her heart. One day, Oshima, a cameraman who lives in the same apartment, asks me to become a model. Eri is attracted to the charm of Oshima, which is 180 degrees different from her husband. Eri, who has finally formed a physical relationship, tries to put an end to her relationship with Oshima in an attempt to get out of her guilty feelings toward her husband.
