As far as I know. I'm only assuming here correct me. Is that she was obsessed with the ex fiance at some point? I think people started to hate her because of it? I'm not sure but maybe it's one of the possibilities
No that's the maids being bitches. She was sold off, she didn't choose him and while she did love him, she was treated like shit by him for 10 years and her family wouldn't take her back.
I don't think that's a valuable reason to be so violent toward her.
In most case, if she really was too much, they should have find a way to help her go over it.
Yeah girl... If they are good enough.. They will help.. But those maids are treating her badly is just them being bitches... No excuse on that... Those maids are just shitty people.
Bitches are just learning the BS their master has treated her for years and they are trained by society to be bashful
The sister is a 'bastard' as Nivea said. But who said anything about her mother? The mother. Could be another noble for all we know and that is what makes the difference.
The situation is complicated to understand. I don't understand how the little sister is better appreciated than the FL when they are both from mothers who comes from a low background. That's... quite strange. I don't understand at all those people. Same with her ex-fiancee. Does he like her or not? Seriously can't they respect their own conclusion rather than being indecisive. He was such an idiot "No I treat you the same way I treat them" and next "Oh my dear friend, how could YOU dare do that to her?!". Be sure of which way you act before saying anything. It would have been better if he just admitted that he treated her bad compared to his friends. Those people are the most hypocrite I've seen in Isekai. Telling FL that she is an hypocrite when they are one. Tch. Such hypocrisy.
