Suppose that in this magical modern society there are magical historical legacies, one is the strange thing like the royal family, and the other is the strange system of monogamy and multiple concubines. Of course, due to the rise of feminism in the latter, this concubine may be a concubine or a concubine. In other words, the mistress may be begged by the husband or the wife.
This is an imaginative short story in the magical royal family.
Sweet pet.
