The once most noble heir to the Wolf King fell in love with an ordinary human girl. On the verge of their wedding, the Wolf King’s illegitimate son seized everything that belonged to the heir. At the same time, the girl was diagnosed with cancer. To save the woman he loved, the wolf heir sacrificed his own heart to cure her. Teaming up with the girl’s best friend, he staged a cruel ruse to force her to break off their relationship with him.
Years later, the girl survived and awakened werewolf powers within her, growing into a powerful werewolf. She was later named the designated fiancée of the wolf clan’s heir, and her child inherited pure wolf blood to become an esteemed royal princess. Having lost his heart, the male lead lost all his werewolf abilities forever. His body turned frail and weak, forcing him to perform backbreaking labor as a slave for others’ amusement.
One day, the illegitimate son intended to make the wolf queen let go of her past heartache and submit to him. As a gift, he sent her a slave—and that slave was none other than the male lead.
