SPOILER kinda
Some time ago, I read part of the novel. I don't exactly remember the reason for the age requirement but it has sth to do with magic and nothing with the ML's personal preferences
I bet the age requirement has sonethibg to do with a sacrifice
If i predict, the ML has to sacrifice wife to save something, and the age requirement is there for that something. He says "no I love her too much" and then through the power of plot armour they will be happy
I'M CALLING IT RIGHT NOW
