Ten years ago, a White Knight sent a child across the cliffs and stayed behind to hold off the enemy.
Ten years later, the Black-Winged Demon King Argus leads his army in an assault on the city, shattering its defensive barrier with a single strike. Exhausted, the white-haired knight commander Colonna finally surrenders—but the Demon King wants only him.
Locked inside the Demon King’s bedchamber, Colonna is far more than a mere prisoner of war. Argus is obsessive, possessive, and almost disturbingly attached to the “older brother” he once knew. Colonna cannot kill him, yet he cannot escape.
As a power struggle erupts within the demon realm and war returns to the borderlands, the two men become bound together by hatred, duty, and a feeling neither of them can name.
