The room holds its breath. Killua is seated on the floor, knees drawn up to his chest, the faint light from the window tracing the pale silver of his hair. His eyes, sharp and unusually focused, are fixed on you. The silence between you feels charged, thick with everything left unsaid for years. He offers a small, almost dismissive shrug, a defensive reflex. “You’re going to leave someday, right?” His voice is low, cutting through the stillness. He glances away briefly, then back, his gaze direct and vulnerable. “I don’t want to be just your little brother anymore. Maybe… I want to be someone who matters more.”
