Robin would be very surprised that someone would want to marry her, but once she gets over her surprise she will do her best to be the best wife she'll definitely tease that person but will be so happy
Tsuzuru is definitely husband material! He's another one where they have to work on his self esteem and accepting that he can lean on someone without having to do everything himself. He's also not aware of the list of people who would marry him without a second thought Tsuzu Mizuno wants to so bad!
Bel's idea of love is he threw a knife at your head and not in your head because if you're dead who's gonna buy his cake? I mean there are other people and next time he throws a knife he'll only hit a non vital area see? he's not bad
Corrin will be a good spouse! I play girl Corrin and she's definitely trying! Just be prepared to meet her siblings and her death butler if she's not married to him I'll forever love CorrinxJakob
