After rebirth, I won't marry you anymore

In her past life, when her father asked Seraphina to choose her husband, she picked her childhood companion Balasar. Yet Balasar was a monster in sheep’s clothing — weak in power, but cruel, who tortured women for pleasure at night. Seraphina endured silently, only to be stabbed to death by her jealous stepsister, who coveted her place as the Dragon Matriarch. Her last sight was the neglected Pendragon avenging her. Reborn, she chooses Pendragon as her husband and vows to help him claim the throne.
