you might be thinking of this one: https://www.mangago.zone/read-manga/suddenly_became_a_princess_one_day/

if the characters you're talking abou are them https://encrypted-tbn0.gstatic.com/images?q=tbn:ANd9GcQIDECC96QIcqKpBy_jXtvqncU18nMRzPTU2uUT6IIg2Me_xzQVlXc0D6XJ&s=10 then yeah it's the manga i linked to
Once in long time,I once saw on tiktok post about manhwa art(there is 50% that it was maybe only novel and it doesn't have manhwa, still if you know what I'm talking about pls tell me)when Fl was getting married(at least I think?) and by her side she had two dads, one is her adopted and the other one was her biological.
Personally I don't know the story, the characters etc, the post had only the art and tbh I have no recollection of how they looked at all!
But I'm sure that it was historically royalty one, the dads sadly weren't gay but I remember that the people in comments shipped them but from what I get one of them if not both should have their own love interest..but maybe no at all, it's fifty fitfy XD
I can't recall properly how they looked but I think one of the dad had black hair while the other had white or maybe just blonde or smth XD
That's about it... Xd
