Hairdresser Eri and accountant Hiroyuki are a remarried couple in their 40s. The two of them go on trips, enjoy meals, and enjoy an elegant life. The only things Eri is worried about are the slight deterioration of her appearance, the recent sexlessness, and the fact that she has given up having children. Eri has no complaints about her marriage, but she should have. However, a mysterious woman appears in front of Hiroyuki, and the couple encounters a mysterious and unbelievable event.
Seiya, Rin, Reira, Takashi, and Nakayama, who attend the same high school, are childhood friends. Rin is so close that she go to karaoke after school and spend time hanging out all the time, but lately, she's a little awkward because conscious of the opposite sex and appearance. The only difference is that most of the adults around them live in a country with the same face. All the adults walking in the city have the same face of a man and a woman - five people in love in such a world.
