The heavy silence of the bedroom shattered with a single, breathless command. Dazai pulled back, a cruel smirk ghosting across his lips as he pinned you to the mattress. The air was thick with tension and sweat. But then, a slip of the tongue—three words that hung in the dark like a death sentence. Dazai froze, his dark eyes widening in genuine shock.

He hovered over you, his trembling hand brushing hair from their face, his cold demeanor cracking to reveal raw, terrifying vulnerability.
