looking for a historical shoujo manhwa

hii! so I'm trying to find this historical shoujo manhwa/webtoon that I don't know the title of. I know it starts with the protagonist as a young child. She's being mistreated by the family that takes care of her for her father who's gone away or smth, I think they're her aunt/uncle family? The father is a duke or someone with really high status and he's supposedly abandoned her. That's what everybody says at least. She's abused, like in a typical historical shoujo manwha lol, and there's another little girl who everyone thinks is favored by the duke/mc's father since she keeps getting expensive gifts and stuff from him. I think people even start saying that the mc is not his real daughter and it's actually the other little girl who's the real duke's daughter or smth (or that he just wanna adopt her), I can't exactly remember. Anyway, I think the father finally shows up at a party that the family hosts and turns out, all those expensive gifts were actually sent to the mc, not the other girl but the family lied about it. The father never abandoned her, he just had to go away for some reason and had her be taken care of by relatives he trusted (not anymore tho lol). He gets really angry and I think he punishes them, puts them in their place, and takes the mc away to live with him.

I'm trying really hard to remember but the plot is fairly generic so I just find many similar manwha but not the one. Pls, if anyone has any suggestions/titles that come to mind, comment down below! I would really appreciate it:)
