When the protagonists broke up

I’m Belita, the villainess in a romance fantasy novel. I transmigrated into a character doomed to a gruesome death after stalking the male lead and tormenting the female lead. If I wanted to survive, there was only one answer: break off my engagement to the male lead before the story began, and leave this city. After executing my plan to perfection, I successfully ended the engagement and even secured a diamond mine as alimony. …At last, I thought I was safe. But then I heard the shocking news that the male and female leads had broken up. The male lead, who used to despise me, confessed his love to me. The female lead began admiring me like some kind of savior. The man originally destined to kill me started flirting with me. And to top it off, a character who didn’t even exist in the original story says he’d risk his life for me. But if the original plot has already gone this completely off the rails… why is it that the chain of events leading me to my death is still unfolding exactly the same way? In this utterly tangled version of the story… can I survive?
