Saito and Kawana Subaru were close friends when they were younger. However, because Subaru came from an affluent family, Saito had to settle for a standard education while Subaru was assigned to the best school. However, he was eventually accepted as a high school freshman through a scholarship program that only a small number of pupils are awarded after years of grueling study sessions. However, Saito’s optimistic expectation of a touching reunion was dashed. Subaru was the most popular student in school and had grown up looking lovely. She was polite to everyone, with the exception of Saito, who she appeared to detest. Saito, who almost regrets attending the school, wishes that their dorm rooms were connected in some way. Their wish comes true magically since it turns that Subaru hoped for the same thing, but in exchange, Subaru loses her self-control for an hour every day. Her true motives are exposed during that period, as her normally suppressed erotic passion for Saito explodes. He wants to make the most of this once-in-a-lifetime opportunity, but doing so could endanger their relationship for the next twenty-three hours.
