To escape a forced marriage orchestrated by the clan elders, the ruling princess of the Vampire Castle purchases a mysterious, mute man—found gravely injured and suffering from amnesia—at an auction to serve as a convenient shield against the union. As she tames him, the man regains his memory, revealing himself to be the supreme Wolf King of the Frost Wolf Clan, who had been reduced to his wretched state after a betrayal. Despite regaining his formidable power, the Wolf King does not leave; instead, he secretly eliminates all her enemies while remaining utterly submissive to her, willingly casting aside his royal dignity to become her loyal hound—guarding both her and the Vampire Castle.
