Replying...
Intro. By defending her family from an assailant and dying, TN is transmigrated to a world of matriarchy, where women are the pillar and those who support the family, while men are the ones who stay at home. The most surprising thing for TN is not the system in which society is governed, the men, who are not only the ones who give birth, but who are divided in two. I pray you, the lower class who have a tendency to give birth to other men. And the jade, the upper class who have a tendency to give birth to women. Not only that, but since women are a low percentage, families are made up of a harem of men, who are seen as nothing more than baby-making machines.
