The Demon Lord's Fiona

In the aristocratic wolf realm, Fiona, the daughter of the Marquis, endures a life of torment hidden behind the facade of nobility. Subjected to severe abuse by her stepmother, Fiona contemplates suicide but clings to her mother's dying words about a mysterious prophecy and her duty to survive.
When Fiona reaches the age of sixteen, she realizes that Arvis Windard, the son of the duke's family and the future alpha, is her destined partner. The Marquis and the Duke's families agree to arrange their marriage once Arvis completes his training in the Elf kingdom. Unfortunately, Fiona's once stunning appearance deteriorates due to ongoing mistreatment. By the time Arvis comes back, Fiona has changed so much that she is hardly recognizable.
Arvis rejects Fiona, revealing that he has found someone more compatible. According to the pack rules, Fiona gets expelled from the pack following the rejection and starts her new life as a rogue.
After leaving the wolf kingdom, Fiona finds herself in the demon realm, encountering the most powerful and ancient demon lord, Aphellios, who initially dismisses her as inconsequential and agrees to her suggested demise. But fate intertwines their paths as Fiona becomes a maid in his palace.
Arvis harbors ambitions for the Elf princess, the guardian of the Moonstone. The Demon Lord's ultimate goal aligns with Fiona's mate, creating a complex web of alliances and betrayals.
However, Fiona's resilience and charm soon pique Aphellios's interest as he grapples with conflicting emotions and a shift in his life purpose.
Amidst familial abuse and a twisted past, Fiona navigates a perilous journey, hiding her true identity and facing the Demon Lord's scrutiny.
As the prophecy is unveiled and people's hearts irreversibly become fixated on Fiona, where will it lead her?
