SDDE-568 Dear – high school student me. Mayu from the art club, whom you’ve always liked and dated, has had sex with all the guys in your class, Azumi Hina

In the winter of my fourth year at university, my classmates met again for the first time in five years at a class reunion. Takao, the main character, has not yet decided on a job offer and attends the class reunion with mixed feelings. His girlfriend, Mayu, who was dating at the time, was also there. There, Takao learns a shocking truth. Mayu had sex with most of the boys in her class. Another face of her that I don’t know.
