I get the feeling Rosa might take both Enoch and Theodore as her husbands. My evidence is the inclusion of the Cardia duchy/Duchess Cardia telling her polyandry is the norm in Cardia. Vivian isn't a possibility any more, they're friends now that the cat is out of the bag. She knows that Rosa cares for her very much as a friend. I guess it could develop later, but I don't think so since the story is moving into revealing her as a female and more into romance now.

I wish this was a throuple ship vivi and enok and our fl i would love that! Vivian and fl is hot and enok and fl is also hot. Imma cry for viví but I think best guy for her is the son of the strong hot duchess (aka fl’ mom’s friend)
