My Husband Turned into My Twin Sister

Gender-swap romance: One mistaken wish turns my wife young again, restoring her to a stunning twenty-five-year-old beauty. Her husband gets his youth back too, but... why is he starting to look more and more like her? Is this what they mean by a married couple looking alike? From then on, the longtime married couple become twin sisters. Their children don't know how to treat them when they come home. And their father, especially, why is he getting more and more delicate?
