Aria’s husband, a doctor, is left brain-dead after a mysterious car accident. Under pressure from a powerful tycoon, his heart is forcibly transplanted into Christian, a ruthless mafia boss fighting for his life. Suspecting a conspiracy, Aria disguises herself as Christian’s seductive yet obedient personal secretary to uncover the truth. Violent and unpredictable, Christian finds himself strangely powerless to resist her—haunted by the heart now beating inside his chest. As his obsession deepens, Aria manipulates his emotions while secretly gathering evidence of his family’s crimes. Just as Christian prepares to propose, he discovers her revenge diary and recordings—realizing his love was a pawn in her plan. Devastated, he spirals into darkness and tries to imprison her. Meanwhile, the truth emerges: the mastermind behind her husband’s accident is Christian’s own father. Torn between love and hatred, Aria brings the true culprit to justice—while Christian is reduced to begging the woman he loves to stay.
