Your thoughts have merit but for the sake of fairness, according to the story the children born from a mother who died giving birth to them are considered cursed children on top of the fact that her father is very influential and loved the mother to such an extent to where that bais he has is also carried by many others. It also explained for the two years of the first te skip she did nothing but prepare to set her plan in motion which required the princess and while I agree her being called a villainess Is a little off putting coming from others but they story did provide some of a reason being her "cursed" nature and her aura described as cold like steel and an off putting feeling she gives off scares people which makes sense considering her past and power. You do make very good points, I just wanted to give the story credit where it was do.

I really hate how it didn’t elaborate on how she was a villainess, if anything it implied that she minded her own business and stayed home for like the 2 years that had any impact on her reputation. And when she ignored her family there was no reaction?? Like they didn’t say anything? Also the time skip was so annoying, like we don’t get to see what she’s actually doing, her relationship with her family that has changed because she doesn’t interact with them, and we don’t see how she was a villainess, so far there is no reason for anyone to think she’s a villainess in the story unless you want to blame her mother’s death on her.
I’m so tired of the “my mother died giving birth to me and now everyone blames me for her death” trope, I’ve seen it in so many manhwa, it’s so overused, and it’s not even the fact that it’s overused. It just literally doesn’t make any sense and usually plots like that are never executed well.
