Raised in the slums of Ebelstein, Derek knows all too well that magic cannot bridge social divides. Through harsh lessons and hard-earned discipline, he rises to become a second-tier mage, scraping by as a mercenary. Life takes a different turn when he is appointed as a magical tutor to Diella Duplain—the temperamental youngest daughter of a noble house, unable to wield magic despite her lineage. Though Derek is her last resort before exile to a convent, Diella clashes with him from the start. Together, will they be able to prove that there's no such thing as a "bad" lady?
