Six-winged Archangel Seraphina spent a thousand loveless years married to Heavenly Commander Michael, who loved her sister, Lyra. When Lyra died and Lucifer waged war on Heaven, Michael died begging Seraphina to let him go in the next life. Heartbroken, she burned her divine power to rewind time. Reborn at the altar, she severed all ties, took Lyra’s place in an ancient pact to marry Lucifer, and gave Michael his freedom. Michael, unaware, wounded her with cruel accusations. After Lyra’s deceit, Seraphina quietly left. On his wedding day, Michael lifted the veil expecting his “true love”—and found Lyra. Realizing Seraphina had sacrificed herself for him, he raced to the Demon Abyss in regret. There, Lucifer proved no monster, but a refined protector. He used his last drop of Angelic Grace to heal her and defended her against his own dark legion. They fell deeply in love, and he abandoned his vengeance for her. When Michael invaded the Abyss to “rescue” her, Seraphina coldly rejected him. In the end, she burned her divinity again to save Lucifer, purifying his dark core. Together they found redemption beyond Light and Darkness.
