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

He hovered above you, his trembling hand brushing hair from their face, the cold facade cracking to reveal a raw, terrifying vulnerability.
