Seduce the Villain’s Father

Ack! I'm trapped in this webnovel, "Brigitte Wants to be Happy!" No prob, I KNOW what's gonna happen so I'll just—wait. I'm not Brigitte? I'm her aunt, Princess Yerenika?! Uh-oh. I'm stuck 20 years before the main plot... and everyone in my generation ends up tragically dead! Her parents, dead. Me, dead. Villain's dad, King Euredian, dead. A-ha! That's the key. I just need to prevent the villain from being born...time to break out some seduction schemes and flirt like my life depends on it!
