I can see how if this story were to be fleshed out, she could be seen as a villainess in her current/altered situation. Examples of some possible reasonings/misunderstandings are choosing work/money over people, leading on and heartbreaking the male MC, and throwing the weight of her position around to make others do what she wants.
But this story still hits the assignment of the anthology. She was born as the villainess, worked at avoiding her bad end, which her efforts and personality made her have a happy ending.
All in all, I like it
