Actually there is divorce in that world since they mentioned it. They probably mean that the specific vow they made is a lifelong binding contract and doesn't have a way to get a divorce
I think it's a novel reason for the other LI to be compulsively like their game selves, I rather like it and hope it'll go in an interesting direction~
Ty for the translation and sending well wishes to the translator~
And a world without divorce is scary because abuses of power and unconditional union obv.
All these precautionary steps they made, how funny would it be that when they meet the heroine she outright doest care about going through a any routes and is just an eccentric business minded reincarnator that wants to make a very successful fast-food chain
Since the translation mentions "Bible" (not sure if its just localization or not), my Christian friends, how correct would you rate the manga in terms of theology?
