What Kind of Vampire Needs to Be Coddled Before They'll Drink Blood?

[Dual male leads + ABO + partial beast transformation + mutually devoted HE + fantasy + healing + cute contrast] The charming young alpha heir of a vampire family is diagnosed with a rare bloodthirsty illness on the day of his eighteenth birthday. To protect all the omegas in the city, the master decides to find Vinnings a personal omega. As soon as the notice goes up, omegas in heavy makeup and drenched in perfume line up outside the castle day and night. Yet Vinnings never shows his face. A few nights later, Vinnings drags a soaking-wet omega in from outside and grits out an announcement to everyone in the castle: this is his personal omega. Wen Lezhou thinks he has gone from one hell straight into an even deeper one. But who would have guessed… The haughty young master gives him the soft bed and sleeps on the rug himself. He eats the breakfast Wen Lezhou can't finish and even bathes him personally… The butler is left dumbfounded. “Young master, you weren't wearing that expression when you brought Young Master Wen home. Back then, you looked ready to strangle him.” Vinnings looks up. “Don't call him Young Master Wen. Call him Madam.”
