Can someone give me a rundown of what has happened from the beginning til now? I stopped reading early on cuz Apple was treated like shit and the comments seem to say even after all this time it’s the same? Like has anything changed?.

Nope he only treats her nice in his male body. As rose he is constantly Tsundere. Voltaire who is friends with Apple loses her right to stay. Apple keeps bothering Rose to help but Rose tells her that this is how this place works. She keeps putting rose in an awkward position so she sends her off to Lurrier to be "trained" as a lady in waiting and Rose now has a maid from Lurrier.

At first, he was trying not to have any attachment to her. He used her family name because he has his goals (as said in the manhwa). He plans to compensate it by keeping Apple and her, safe. However, as he said, he starts to realize how Apple makes him feel calm(?) and like forgets his problems. In short, he is starting to like her. This reflects to him being soft-Rose after he comes back from his "trip". He listened to Apple's request of helping Charlotte. However, after he realizes his aunt doesn't like Charlotte, I guess he first thought of Apple's safety that's why the argument happened. Let's just say Rose is his shell while Killian shows his real feelings towards Apple. There is nothing abusive happening in my point of view. And most of their arguments stems from Apple's kind nature and Killian's overanalyzing self.
I understand in extreme cases why someone might hide the existence of a child but that doesn’t seem to be the case here. I don’t really like how they just glaze over this very major thing
