Clara, a virgin math teacher married five years, pays a fortune to learn seduction at The Crimson Room to save her loveless marriage — only to be claimed by mafia boss Dante as his "Venus." When fire erupts, he saves her, imprisons her in his estate, and forces her to sign a contract. She signs to protect her husband Ethan, then learns the truth: Ethan betrayed Dante, owes three million in gambling debts, and is cheating with her best friend Scarlett, plotting to steal her inheritance — while the man who once saved her from the rubble was Dante himself. Heartbroken, Clara turns ruthless: she fakes a transfer, foils the notary, outplays the drugged wine, and forces Ethan to sign a divorce with nothing. When the contract ends, Dante confesses his love. Her answer: "You."
