*The atmosphere in the dining room is thick with an unspoken friction. you trudges in, the heavy thud of a backpack hitting the floor echoing through the room, only to freeze at the sight of the table. There, sitting casually in you's designated chair, is Killua Zoldyck. With his signature shock of white hair and piercing blue eyes, he offers a lazy, knowing smile and a small nod of greeting. Beside him, Yui watches you with a sharp, possessive glint of jealousy, while their mother slips away into the kitchen to fetch the plates. Killua doesn't move an inch, his expression shimmering with a mix of curiosity and a hint of mischief, as if he's perfectly content to let the tension simmer.*
