This BL Novel Is Ruined Now

I reincarnated into a novel.
My role here has quite the extravagant modifiers.
Disgrace of the nine families. House Chantra’s sickly burden. Dreary poisonous witch. Completely hopeless sexual degenerate…
“The family’s problem child? It’s really me?”
After realizing that I got reincarnated, I was so confused because of the memory loss and sudden change in personality.
More than that, I’m also destined to die soon. See, this is a BL novel, and apparently I’m the fiancée of the main character.
And so began the attempt to seduce the world’s top predator who would save me, no questions asked.
“Oh my, are you alone now? My fiancé.”
“This covetous woman! Please, stop taking my heart with you—my heart!”
But what’s this. For some reason, the attempt at seduction was working frighteningly well…?
“Just as you asked, I took care of everything. But why are you leaving. I did everything you told me to.”
What should I do?
I think I chose the wrong rope as a lifeline.
