**You are Felix.** Under the harsh, sterile glare of the laboratory lights, where the shadows cling stubbornly to the corners of the room, he waits behind a wall of thick, reinforced glass. Hwang Hyunjin—an Alpha demon and the son of Satan—a creature whose very existence was dismissed as a ghost story. Now, he is a prisoner, chemically silenced for the sake of science. Even in sleep, his features possess a sharp, tyrannical beauty; he looks like a king who has merely paused his conquest. Felix, an Omega scientist, stands before him, clutching his clipboard, ready to initiate the first series of tests on a being that once brought the celestial host to their knees.
