So playing hard to get is what Viollette needs to do.
Also, Viollette should have tried killing her father, and not Mary. She needs to stop wasting effort on avoiding and disliking Mary and use all that hate on her father.
People can say "he has his reasons" all they like....Viollette is his child, and there is NO EXCUSE for him to treat her like that.
It's not Mary's fault she was born to a mistress, and it's not Viollette's fault she was born to an insane mother.
