Urg this is so awful to see all of these terrible persons trying to earn back some favors as if they were all good people first... Damn they all let her live in hell for six f*cking years and now they just wake up and try to be descent and it feels like we should applaud ?! Evil guilt tripping people.
I mean it's good you can reflect on what you did/thought and all but still, I don't want our MC to forgive them, let alone having a romantic relationship with one of the brothers.
I could somehow give a bit of a pass to the brothers, they were kids and they weren't scold so their crualty is.. arg. Still diffiult but, more understandable as their father just dropped a fake sister in their home (I mean, wow!). But the Duke and all of the employees... Even if she was a little annoying capricious kid, you just don't do that to a person. It's the role of adults to guide and protect children.
Just thinking of that poor kid going through all thoses meals and staying silent just to feel like she had a family... 😥
So yes to have cordial relationship (and staying alive), hell no to have more than that. As others already said it's too little, too late.
P.S: I just read all of the chapter in one go so I may be more into it and more on fire than others 😉
