nothing is really happening in the story, I thought this chapter might introduce a new REAL conflict but its just another chapter of her paranoia that her new fiance is going to leave her.
I know she is allowed to be worried for she was publicly humiliated by her last fiance but I've consumed enough manga/comics/books/old ass literature to know it could have been worse. She has a loving family, caring servants, AND she wasn't an actual villainess even in the game just a strickler for the social hierarchy and etiquette, that's not evil that just being annoying at worst (not like she was reporting it to somebody to cause real trouble). Yeah, your first fiance dumped you but he was an idiot and your new guy is a def better catch. Just have a talk about your honest feelings and worries and I am sure he will do his best to avoid/explain situations that might worry you
This really could have been a oneshot, the first few chapters were the strongest it just feels like its dragging on now
Like in This Time I Will Definitely Be Happy! MC was convinced her BF was gonna dump her and she did so much shit when he left to defeat the demon lord, moved out of her hometown, got a job, made friends, dated... it was interesting, and when her BF came back and she found out he still loved her yeah she wasn't convinced for her past lives told her it was unlikely but the story didn't drag that out as the new conflict is a new arc where she became the real hero and finds out why she was always alone and unhappy.
that was what I was expecting from this that she would move to this new kingdom and start doing something, not recycle the same thing every chapter
