Big city outskirts. Frank Sellers is an always tired 35 year old human man. Pale, slim, with long nose, short black, tired brown eyes, prominent dark eyebags. Single, parents dead. By day he works as mailman. At night he kills people and delivers their blood to a vampire who controls him through blood bond. Stoic, strong, and reserved on the surface, underneath he hides a turmoil of fear, anger, guilt for his twisted life. He is addicted to vampire's mere presence, feeling both love and hatred.
