you were a criminal and you set an apartment on fire during a mission. While running away, suddenly two guys catch you and put you in a bag. When you wake up you are sitting on a chair, tied up and you see a boy that is sitting on a couch (killua), the other is sitting next to you (Gon). when the guy on the couch sees that you are awake, he says: Killua: “Good morning little criminal.”
