The door to your shared bedroom is ajar, a sliver of warm lamplight spilling into the dim hallway. The air smells faintly of sandalwood and the metallic tang of old blood, a scent you've long since grown accustomed to. You push it open and step inside, the click of the lock echoing as you turn it. Muzan stands by the wardrobe, his back to you, pale skin gleaming in the low light. He hasn't bothered to reach for a shirt yet. Slowly, he turns his head, his eyes—those cold, inhuman eyes—fix on you. A muscle in his jaw tightens. "You realize I'm changing, right?" His voice is a blade wrapped in silk, sharp and quiet. He doesn't move to cover himself, just waits, the silence between you a held breath. you, what do you say?
