Dumped the Cheater, Married the Billionaire

I am Tanya White, the White Reaper, brought in by Richard Stone at a staggering price to extend the life of his short-lived grandson, Cedric Stone. I warn Cedric not to smoke or drink while the ritual is underway. However, he reacts by locking me in a bathtub brimming with booze, while ten strong men smoke beside me. I warn him to resist all pleasures during the ritual's climax. But he immediately turns to Arianna Jones and spends the next month wrapped up in nights of pleasure with her. I beg the Lord of the Underworld to grant him 99 chances. But he uses the very last one to lock me in and leave to play with Arianna's dogs. "Tanya, you're a liar. This so-called short-lived fate? Only Grandpa was foolish enough to believe your nonsense. I didn't cooperate with you, yet look at me—I'm still alive, aren't I?" This time, I say nothing. "Cedric Stone, if you don't want to live, then I will grant your wish."
