The assistant was married but her husband was an abuser idk what happened but they separated and that’s why she said it’s her second marriage so she’s over 20. I think the marriage rule might be for everyone because even the brother was looking for someone to marry. This is just what I think from what I saw so take it with a grain of salt.(￣∇￣")
Marriage law is only applicable to women, there are many men in their 40s who are unmarried like Mr. Mu. It was talked about on the night of the ball after the end of military training. ヾ(❀╹◡╹)ﾉ~
At the beginning, when her Marriage is nearly sabotaged by her "sister", it is mentioned, that marriage at 20 is only mandatory for women, because there are fewer women than men and the government want's to rise the birthrate.
A lot of men stay single for life, because there are not enough woman.
It affects only Pure Human women that reach the age of 20. If they're part beastman it's not mandatory.
It's basically once you turned 20 you'll be married, right? Does that only affect the women? If so, what about miss assistant? I think she's older than 20. Did she has a partner in the past and broken up? Is the marriage thing only in effect when you're 20? Did they just don't care after that?
