I am just sharing the Spoilers and even I find this plot twist a little too far-fetched and random.

Ngl I can't recall besides her having altered memories of some incidents regarding her twin. And it not really presented as if Laurencia is the narrator imo. What I find strange is if she is that dumb why was it her that was given a chance to rewind time. And if Erica was so smart then why were her schemes so awfully executed. It was like watching a 3rd rate villainess

The FL Laurencia Aztane herself.

I get the argument that the dead parents and the living incompetent grandpa are the real Villains or are responsible for not educating/helping these Twin Sisters enough.
But I still don't have much sympathy for the FMC who, as a child, deliberately pushed Actual Genius Ercia down the stairs and weaponized her self-harming to get attention.
Ercia still loved her and pretended to fail at things and be sick, so Laura can get all the glory and become the Heir.
After the death of the parents, Laura conveniently erased her memories, started to believe herself to be a natural talented Businesswoman and forgot all the sacrifices Ercia did for her.
Now I am wondering: Why does this Girlboss Bitch deserve Regression and a Duke/Prince?
There is also some criticism on Reddit that there are not enough hints about this unexpected plot twist.
