My Contract Husband Is A Cursed Billionaire

“As the eldest daughter of the Sharp family, I was treated worse than a stray dog, while my younger sister Seraphina was their precious princess. When the family needed someone to marry a dying billionaire heir, they naturally chose me to take her place. To force my consent, my brothers held a peanut butter sandwich to my face-knowing it was a lethal allergy-while dangling my EpiPen just out of reach. On speakerphone, my own mother sighed in annoyance. "Let her die. It might be for the best." I choked out an agreement just as my throat closed up. But the forced engagement broke my sacred mystical vow, causing me to violently cough up my own lifeblood. Seeing the blood, Seraphina dramatically fainted. My brothers instantly carried her to the hospital, stepping over my dying body and leaving me to bleed out on the cold marble floor. I had to use a forbidden blood rune, draining my last ounce of strength, just to survive the night. Even the mystical Order I served offered no comfort, calling only to demand I secure ten billion dollars for them or forfeit my soul for eternity. Abandoned by my blood family and my spiritual master, I was completely alone, left with nothing but a broken body and a ticking clock. But they made one fatal mistake: they let me live. I turned to the dying heir they forced me to marry, a man plagued by a dark curse only I could cure. "I will be your wife, and I will save your life," I told him. In exchange, I would use his unimaginable wealth and power to make everyone who threw me away pay the ultimate price.”
