Rafael De Carlies was merely an ordinary soldier in the eyes of the Hurbret family, someone considered lowly and powerless. No one knew that behind his simple appearance, he was the heir to royal blood and a legendary sword master, possessing dark magical powers capable of subduing the demonic creatures that threatened the kingdom's borders. To fulfill his mentor’s last request, Rafael married Annette Hurbret—a woman who never truly loved him. For three years, Rafael secretly protected the Hurbret family from danger and built their wealth, hoping that one day he could have the family he dreamed of. However, his happiness was shattered when he discovered Annete’s betrayal with a marquess. Annette and her family scorn Rafael as a parasite and mercilessly divorce him.

As the magical protection he had provided disappeared, demonic creatures returned to destroy the Hurbret family, and Rafael vowed to repay all the betrayals they had inflicted.
