The Substitue Groom is a Mafia Daddy

Anna's father has left her family buried under a mountain of debt, and to settle it she is pushed into a marriage she never wanted with Valentin, the merciless head of a powerful mafia financial empire. He is cold, domineering, and used to total control, a figure the underworld fears. When a fateful accident drags Anna into his private chamber, a room built around dominance and surrender, the two find themselves caught in a tense and dangerous game of desire and submission.
