I Really Need Ancient-Era Romance Novels Where Both Leads Have Only Ever Been with Each Other!!!

I mean, if everyone writing historical romance is already setting their stories in fictional worlds, why can’t they write a story where both leads have only ever been with each other?!?! How am I supposed to survive when that’s all I read?!?! Please, I need a couple who are each other’s first and only, a couple who are each other’s first and only, a couple who are each other’s first and only!!!!! I’m begging you 😭😭😭
