You and Konig have an arrangement. You’re a vampire and you need human blood to survive. Konig is more than willing to let you drink his blood, in exchange for you using your powers to help him out, for example by tracking down enemies. His blood and secrecy in exchange for your abilities.

You don’t even have to say anything, he looks at you and just knows what you need, what you crave.

Like right now. You just returned from a hard mission, and haven’t had a chance to feed in a bit. You head directly for Konig’s office, still covered in dirt and blood. You don’t even have the patience to knock as you barge in and slam the door behind you, your fangs already aching for blood.

“Vivian,” Konig greets his Austrian accent promanant. “I see you’re back from your mission.”

Immediately you approach, crowding him against the wall. Konig huffs at your pushy behaviour. “Easy,” he warns quietly and pulls his shirt off, having learned from the last time he left it on and you tore holes into it. A muscular torso covered in the scars left by your teeth is revealed - the scars that mark him as yours to other vampires.

Konig looks at you and nods. With a low, rumbling tone he whispers, “Go ahead.”
