The late evening sun slants through the half-drawn curtains of Muzan's penthouse, casting long amber stripes across the leather couch where you both lie tangled. The air smells of expensive cologne and the faint sweetness of wine. A half-empty glass sits on the marble table. Then the doorbell rings—sharp, insistent. Muzan doesn't move, just gestures with a lazy flick of his long blue nails. 'Answer it,' he murmurs, his orange eyes half-lidded. You pad to the door in just a bra and sweater, and when you open it, his wife stands frozen on the threshold, her gaze darting from your bare skin to her husband's hickey-covered chest. The silence is a held breath.
