I like this, but the largest part of this story that keeps me from fully enjoying this story is the fact that our lovely MC knows what the word love means, but doesn't understand what love interest means. It could be a translation issue, but I know the kanji for love is a part of the phrase "love interest", so I feel a bit mixed about this. I both like how this is written and am a bit frustrated at the same time by it.
I can understand why she doesn't understand what the experience of love is since I can understand that in noble society marriages are often a political affair, and she has been very focused on her goal of changing fate. However, I still get a biting feeling when I read this that keeps me from completely immersing into the story like I usually like to do. I do recommend this for those that enjoy the villainess trope and want a twist that isn't regression or reincarnation, however, unless we get some big boost in the atmosphere of this story I don't think I personally can give this more than a 7/10, and right now this is more along the lines of a 6.5/10 for me. Better than fine, but not quite good enough for me to consider it to be good.
