Cordelia, the eldest daughter of the prestigious Vasquez family, one of the Eight Sacred Houses, faces a life she never chose. One day, she is sold to the Abrams family for money, only to endure relentless mistreatment from her in-laws. Amid this turmoil, her unfaithful husband suffers a tragic accident and loses all his memories. But within his body now resides Leonard Atirei, the legendary archmage who was believed to be dead. Seizing the opportunity for freedom, Cordelia presents Leonard with divorce papers, only to hear him say, "If you want my signature, you must obey my terms." Finding the arrangement unjust, Cordelia proposes her own deal, rather than reveal his true identity, Leonard must become her mentor. Though he resists repeatedly, Leonard is eventually swayed by her relentless determination, and the two form a formal contract of master and disciple. Yet danger looms. Exploiting her husband’s amnesia, Cordelia’s mother-in-law and her brother plot to seize control of the family. Now, Cordelia and Leonard must foil their schemes and embark on a perilous journey, not only to protect the family but also to avenge Leonard’s past at the hands of Maximilian.
