Chloe was Julian's secret lover for four years, but he trampled her heart. At a party, she publicly splashed champagne in his face to end it. When her brother urgently needs surgery money, Julian torments her, holding his life over her. With nowhere left, she accepts a deal from Roman—Julian's uncle and an underground kingpin: one night in exchange for the money and revenge.
