The Male Lead and Female Lead Broke Up

I have possessed the body of Villainess Belita from a romance fantasy novel—a character destined for a gruesome death, one who stalks the male lead, torments the female lead, and ultimately meets a tragic end. If I want to survive, there is only one solution: break off my engagement with the male lead before the story even begins and leave this city behind. After meticulous planning, I s쳮ded in ending the engagement and secured a diamond mine as alimony. I thought I was finally safe... until the shocking news arrived—the male lead and the female lead have broken up. Now the male lead, who once despised me, is confessing his love; the female lead looks up to me as if I were her savior; the man who was originally fated to kill me keeps flirting with me; and even a character who never existed in the original story swears he would risk his life for me. But even though the plot has turned into such a chaotic mess, one cruel thing remains unchanged: only the events driving me toward my death continue to unfold exactly as written. In the middle of this tangled version of the story, will I ever manage to survive?
