The Alpha's Ruin — Episode 18

Pureblood hunter Seraphina accepts contract to kill Alpha CEO Kael. She fails when he recognizes her fated mate mark. Trapped as his secretary, she discovers his lethal curse—and that her “dead” father Magnus is alive, secretly controlling her life and experimenting on her twin brother Caelum. Forced into uneasy alliance, Seraphina and Kael raid Magnus’s bases, free caged cubs, and learn her sealed wolf spirit can slow his curse—but at cost of her own strength. As resonance deepens, Kael secretly offers to trade his CEO position for Caelum. When his curse spirals, Seraphina performs risky transfusion to buy him 72 hours. Orion reveals this “Borrowed Life” binds their fates forever. With Magnus readying final altar, they must decide: walk in together—or die alone.
