HMN-875 A room you can’t leave unless you complete the task. Four men and one woman, all gathered and trapped in a cramped space after being told their debts would be wiped out. Because the rule was that each release would reduce the amount they had to repay and allow them to leave the room, the only woman there was repeatedly targeted. A story about office worker Rei Kuroshima.

Men and women are confined in a cramped room with only a bed, all of them people who have been judged to be in debt and unable to repay it. As part of a social experiment to address the declining birthrate, the rule is that if a pregnancy is achieved, the debt can be erased. If conception is successful, they can leave the room. The only woman is Rei, an overworked office worker with debts to multiple consumer lenders after spending heavily on host clubs. With only one woman in the room, the only way out was inevitably to try to conceive with her.

A shameless man who takes advantage of the situation, a self-proclaimed protector who wants her but tries to keep her safe, and a timid man who cannot bring himself to act out of guilt. Their despair, inner conflict, and desire collide in a chaotic group encounter.
