Momoki Shirakawa became the bride of Chikage Kurotaki in the neighboring village overnight due to a curse that forces the villages to allow marriages between them and there being no women.
Overwhelmed by the pressure from both families, they accept their destiny, But when Momo rejects Chika in the wedding night (who was secretly not opposed of the idea), they try to run off but get caught and sent back to Tokyo. After distancing and avoiding each other they and others get sick - showing that the curse work, so they have to fullfil the ceremony of a wedding night. Following Momo gets more affectionate and cools etc. And on the weekend they start to „prep“ until they finally do it. When China wakes up the next morning he can’t find chiko and thinks that he was dumped - consolidating with a colleague instead, only to find out that child asked his parents for his true hand in marriage
