A world where marriage had became law. This law was enforced to decrease the chances of children being Quirkless in hopes that society will then become 100% superhuman. Letters are sent out at a young age in hopes to prevent future struggles. That being said, loving someone who is not your destined partner is taboo. -💞- (Y/N) (L/N) had just gotten her letter on who her marriage partner is! But she doesn't quite agree with the results that the scientists had pulled for her, since her heart was already stolen by someone else!
