How to Marry Brint?

[LucianErebus]

Hey it's been too long,

but as said in the title, how do I marry Brint again? Like I haven't touched this game for about like 5 months or so, and I feel so far behind!
Attached her is my file, could you provide me a step by step guide on how to marry him?

You have to have sex with Brint at least 10 times and complete all of Brihaus. You don't have to romance Rina or Cassia, but it does need to be completed. Not sure what else, but that's what I can remember
