Human woman Ivy married Lucian, the heir of a werewolf family, and helped him suppress the family's hereditary curse through regular blood offerings. Over seven years, she accompanied him in rebuilding the family's power and bore him a mixed-blood son, yet she was always regarded by aristocratic circles as an inferior human wife. On the eve of her son's birthday, Ivy came home and caught her husband biting the neck of a girl he had been helping, forming a pact with her. Her husband argued that the girl was merely helping him get through the night of the full moon, but her son said, "She can live with us for hundreds of years—you can't." After Ivy voluntarily applied to dissolve the marriage, she met the Wolf King Adrian and the human girl he had adopted. Seven years ago, Adrian had fallen in love with her, but left after she chose Lucian. Now, he gives her shelter and protection, and also helps her uncover the truth.
