Vampire!WWX AU where LWJ sells his blood to the vampire blood bank...

It's simple, almost painless, and quick. It doesn't cover all of his expenses, but its worth it.
That is, until he gets the attention of a vampire whose name is known to everyone: Yiling Laozu.
He doesn't check it. He came up here to get some peace and quiet from the birthday party going on at full volume downstairs, and checking his phone is nothing near peaceful.
He can't.
Because there's a man on the rooftop with him.
What he can discern, however, is how much /noise/ the man makes.
LWJ wonders if he's a singer.
He frowns. Thats weird. He was just there today, selling his blood. He doesn't usually get feedback, or even check-ins from them. They get what they need, inject the healing serum on him, and let him go.
"You have been selected as a special provider for a very prestigious client! The Yiling Laozu has chosen you to be a part of his regular colaborators!"
LWJ raises an eyebrow when he sees the name.
