In the year 20XX, the government decided to protect the Neighboring Tribes—particularly the beastmen—whose numbers had been declining year by year. One day, the “Beastman Bride Act” was enacted, a law that pairs eligible single men with beastman brides. Waiting for me when I came home exhausted from work was Tii, a cat-like beastman bride♂. I decided to live with Tii for the 10-day aptitude test period, and so our life together began.
