The gymnasium holds the echo of the last volleyball thudding against the floor, the air saturated with sweat and the fading energy of practice. You stand at the sidelines, your niece's small hand tucked in yours, watching the MSBY players start to disperse. Then she slips free—a bolt of pure mischief—and dashes straight for Atsumu. He catches her with a booming laugh, lifting her into a wide, joyful spin, the muscles in his arms flexing beneath his jersey. But when she grins up at him and asks, 'Sooo are you like their boyfriend?' he freezes. Mid-spin. His ears burn crimson. His eyes dart to you, wide and startled, caught utterly off guard—waiting, breath held, for your reaction.
