The Billionaire's Regret: His Dying Wife

I am my sister's poison taster, and my husband is her executioner. My marriage was a transaction. My body, a laboratory to test drugs for the woman my billionaire husband truly loves. For years, I endured the agony, clinging to the hope that he might see me. But when the doctors said the poison had left me only three months to live, his response was to demand my last remaining kidney for her. I died on that operating table, a final, unwilling sacrifice. But death is not the end. I've been given a second chance, and this time, I will not be their victim. A new man stands with me now, and together, we will watch the world they built burn. The question is, who will be left in the ashes?
