The story takes place in Sakura, a country where the birth rate has collapsed, in 2036. On the eve of the "Marriage Ban" taking effect, a law that forbids women from attending university, permanently bars unmarried women over twenty-five from marrying, and orders the removal of the uterus of any woman who has not given birth by thirty, the cold official who publicly denounced her and had not contacted her for three years shows up at her door, drenched from head to toe. He thrusts a marriage contract at her and orders her to sign immediately. This is no proposal. It is the only way out of hell, carefully planned by him and disguised as marriage. In the final twenty-four hours, she will discover that all his hatred was a lie, and that this sham marriage will become the most heroic uprising against the age they live in.
