if the original villainess time traveled or something it would make her fear and complete lack of trust in her father make much more sense. she experienced him telling her to commit suicide (as far as she knew), after all.
we could also see much more character growth out a heroine who realizes her toxic behavior and sour social rep contributed to her death, and thus works hard to change. learning to form better relationships would tie in directly to reconciling the misunderstandings with her father. you can really feel the self-insertness of the reincarnated FL, which just isn't as compelling...but then again I guess that's the point of these kind of mangas isn't it lol
