Honey, Why Can't We Get a Divorce?

I've become 'Ophelia Regen,' the villainess in a trashy romance novel. Before I end up falling for the schemes of the protagonists and facing a pathetic demise, I want to hurry up and divorce Ophelia’s husband, 'Silvester Regen,' and find my way to freedom. But the conditions he set are ridiculous.

"Ophelia, you want a divorce? Try to win the crown prince over."

How am I supposed to charm him when the original female lead is right there? Plus, in the original story, Ophelia ends up getting killed by him!

But I still have to pull this off, for my successful divorce! How on earth am I going to seduce a crown prince who hates me more than a fly?
