Eternal Bride

"Elena, a maltreated human girl with rare golden blood, is sold to vampire prince Damien as a blood servant. Damien shields her fiercely, as she is the reincarnation of his lover killed by rebel Raphael three centuries ago. Plagued by jealous castle maid Vera and greedy human relatives, Elena learns her golden blood puts Damien in constant peril. She voluntarily turns into a vampire and trains to wield her special power, with her silver locket reviving her lost past memories. Traitor elder Marcus leaks intelligence to Raphael, who launches a full-scale siege. In the final fight, Elena recovers all memories and blocks the fatal blow. She and Damien slay Raphael together. The two hold a grand wedding and welcome their baby. Standing together on a twilight tower with their child, they end three hundred years of lonely waiting for eternal love."
