Synopsis：To survive, Xander Quinn must find the one woman who carries dark energy—Sienna Jade—and sleep with her, even if it means taking her life. He hides the truth, marries her, and secretly pays for her grandmother’s medical bills. Grateful and unsuspecting, Sienna gives herself to him, unaware that their marriage is a deadly bargain from the start. Unexpectedly, Xander falls deeply in love with her and frantically searches for another way to save himself. Before he can undo the damage, Sienna discovers the cruel truth: her love and life were just a sacrifice for his survival. Shattered, she tries to escape, only to meet a tragic end. Yet, thanks to a mysterious pill left by her grandmother, she miraculously comes back to life—at the cost of her sight. Seven years later, Sienna returns with her young daughter and unknowingly crosses paths with Xander again. Not recognizing them, he ruthlessly torments mother and child, until the truth finally explodes—she is the woman he once destroyed, and the girl is his own daughter. Devastated and desperate to atone, Xander conceals his identity and tries to reenter her life. But when Sienna recovers her vision, she finally sees the face of the monster who once stole her love, her future, and her life.
