i haven’t read all of it but is she gonna get with her sister’s husband?

I'm pretty sure he's only her sister's fiance, also

SPOILER
the sister who's his fiancé was actually a traitor i think and was the one who helped start the war according to some of the spoilers in the other comments

The spoiler does not get hidden :(
