Bloodbound Bride：I Was the Duke's Blood Potion

"I was the daughter no one wanted. Then the Dark Blood Duke claimed me in front of the entire court. Edwin declared I was his fated bloodbound mate — the one his ancient blood had longed for across centuries — and carried me away to his castle deep in the Eternal Forest. He filled a night garden with roses that bloomed only under the blood moon and gave me a wedding that made every woman in the kingdom envy me. For the first time in my life, I believed I was chosen. Loved. Safe. Seven months pregnant with his heir, I attended my father’s birthday feast. That night silver fire erupted. My father and brother only screamed for Kelsey. They dragged her to safety while I choked on smoke and called their names until my voice broke. Edwin was the one who carried me out of the flames. In the Blood Healing Tower I finally overheard the truth they never meant for me to hear. Kelsey was not dying. She had faked the blood core degeneration all along. And the childhood savior Edwin had worshipped for centuries… the one whose piano melody still lived in his blood… had never been her. It had always been me."
