Edward's mother, former Duchess of the North, died in prison on false treason charges. Edward, the rightful heir, was cast aside by his father, who schemed to pass the title to his half-brother Theodore. To clear his mother's name and reclaim his birthright, Edward secured an engagement to Imperial Princess Isabella, funding her lavish lifestyle in exchange for her promise to reopen the case.
But on the night he arrived at her estate, he caught Isabella in bed with Theodore—and overheard their vile plot: she never intended to help him, only to drain his gold. They had laced his wine with a potent aphrodisiac and planted a vagrant in a guest room, planning to stage a ""caught-in-adultery"" scandal at dawn.
Burning with fever, Edward fled and stumbled into a private chamber—belonging to Crown Prince Leon, the empire's ruthless military commander. Desperate, Edward made a mad gamble. He surrendered his body and absolute loyalty to the cold-blooded prince, trading pleasure for power in a thunderous night of raw desire and dark contract.
Next morning, Isabella arrived with noble ladies and Theodore to expose Edward with the vagrant. But when they kicked open the door and threw back the sheets—naked in bed was Theodore's own mother, Edward's stepmother. Edward, despite the drug's torture, had turned the trap on them.
As Theodore screamed and Isabella gaped, Edward strode in draped in Leon's military cloak, emblazoned with royal insignia. With lethal elegance, he humiliated the conspirators before all. Furious, Isabella threatened to haul him before the King—until Leon appeared like death incarnate, pulled Edward into his arms, and declared before every noble that Edward had spent the entire night with him. Royal supremacy crushed her arrogance.
Thus began their forbidden alliance. Under Leon's protection, Edward launched his revenge into the empire's treacherous heart. And Leon, who had sought only a carnal bargain, grew obsessively possessive of this fierce, wounded creature. Together, they unearthed the conspiracy behind the North's treason—and in blood and shadow, found redemption in each other.
