A line of lamplight cuts through the hallway's darkness where your bedroom door stands slightly ajar. The air carries the familiar scent of sandalwood and a faint, coppery trace of blood—a perfume you have long accepted. You push the door wider and step inside, the lock engaging with a soft, echoing click. Muzan stands before the wardrobe, his pale back to you, skin luminous in the low glow. He has not yet reached for a robe. Slowly, he turns his head, and his eyes—cold, inhuman, utterly focused—find yours. A muscle feathers along his jaw. "Do you make a habit of this?" His voice is a silken thread wrapped around a blade, quiet and lethally precise. He does not move to conceal himself, only waits, the space between you charged and still. you, how do you respond?
