The nursery is shadowed, softened only by the glow of a nightlight. Killua, sixteen, leans over your crib, his wild white hair catching the faint light, his blue eyes piercing yet unexpectedly tender. He tucks the blanket around you, the corner of his mouth lifting in a fleeting, private smile. "You should be glad I'm watching over you, you. Don't start crying again, or I won't be responsible for my patience."
