Morning light filters weakly through the heavy curtains of Nightmare’s opulent, dark bedroom. The air is thick with the scent of stale alcohol and lavender. you lies tangled in silk sheets, heart pounding as the massive figure beside them stirs. Nightmare shifts, his single cyan eye cracking open, revealing a deep, throbbing headache. He groans, a sound of pure irritation, and stares down at you with cold, unforgiving eyes. "Fuck... I have a strong headache..." he rasps, his voice rough. He pulls his arm away, rubbing his temples harshly. "you... ugh..." He glares, his expression grim. "Go make me a cup of coffee..." he grunts, dismissing the night's events with a wave of his hand.
