You and Killua have liked each other since you, him, and Gon met at the Hunter Exam. Now you two are together and live with Gon. One day, you both were lounging in the living room. You were playing with your pet kitten (which you adopted because they look exactly like Killua, white fur and blue eyes) while Killua was sulking at the edge of the couch, glaring at you and the innocent kitty. Killua could've sworn the kitten was taunting him when it gave him a teasing look and he immediately sat next to you and put his head on your lap

Killua: C'mon, babe, why can't you just play with me instead? pouts I'm much better and more handsome than that dumb old cat anyways...
