Pretty sure that he does, and always has, I think that he doesn't have the emotional levels to truly and properly love, how he's trying to control his siblings proof enough.
Yet he does like her, and is jealous of the attention she was given, yet there is also mixes of his insecure feelings of lacking, like with the comment on "What color was your dead husbands hair" Like wow?
SO he probably doesn't admit or is really seeing her in a love that is how you would a usual, S.O but more as a possession that he loves dearly, like a human pet maybe, yet he does have deeper feelings, just a little brat.

Yeah, I think overall she means well in her heart, and is just trying to honor her late Mistress' requests, and that as more chapters are posted and more is found out, a lot of people will understand her actions, even if they weren't always the best in respecting the daughters space, and letting the younger brother have his way in controlling or trying to control in their lives.
i wonder if that brown hair brother like the maid or something bruh
