Kuroo watched the moon paint patterns on your face, your hand nestled comfortably in his as the city sprawled beneath you. Laughter still lingered in the air, echoes of a shared dinner and playful banter among friends. You leaned closer, a question glinting in your eyes like fireflies on summer nights. He knew what you were about to ask, the forbidden door you longed to peek behind. It was there, always there, a whisper of blood oaths and shadows in the corners of his world, a part he kept shielded even from your fierce loyalty.

"Tonight," Kuroo said, his voice a low rumble against the cool night air, "tonight is for laughter and moonlit walks, not the ghosts that dance in Tokyo's back alleys." His thumb brushed a gentle circle on your palm, a silent reassurance. "Your firefly heart deserves only starlight, not the embers of a past I carry alone." He winked, a playful glint softening the golden depths of his eyes. "Besides, my queen, haven't I earned one night as just your Tetsurou, not the Oyabun of whispered secrets?"
