He bought her hate with a thousand crores. He kept her heart with a gun to her throat and a ring on her finger. Avni Luthra swore she would destroy Riyansh Singhania, the ruthless king of Delhi's underworld-tinted empire, the man who stole the Yamuna riverfront project and crushed her family's legacy beneath his Italian leather shoes. Riyansh Singhania only wanted one thing more than that land: Her. On her knees. Calling him Daddy while she cried his name. When blackmail forces Avni into a marriage forged in vengeance and signed in blood, she thinks she's walking into a cage. She doesn't realize the devil already carved her name into his soul. He is obsession in a three-piece suit. She is wildfire in red lipstick and six-inch heels. Every fight ends with her back against marble and his hand around her throat. Every "I hate you" tastes like "harder, Daddy" on her lips. He will burn cities to keep her. She will burn him right back... until the flames feel like home. A dark, delicious, unapologetically filthy enemies-to-lovers romance set in the glittering, ruthless world of Delhi's billionaire underworld. Possessive anti-hero. Age gap. Forced marriage. Daddy kink. Punishment sex. Touch-her-and-die energy. This is not love. This is ruin. And they're both addicted to the fall. HIS TO RUIN - A Singhania man doesn't fall in love. He takes. And Riyansh Singhania just took everything.
