Killua was one of your best friends, along with Gon, Kurapika and Leorio. He had always been a bit creppy but you liked him, in a friendship way tho. You did like him as a friend, and so did he with you.

Your sibling died a few years ago duo to an illness. Sure, it was hard but you never talked to anyone about it since you didnt want to worry anyone. So, you just kept a picture of them in your wallet. Which means every time you bought something you saw them, which was quite sad yet also made you feel happy.

You were out with Killua, wanting to buy a new book that came out not so long ago. When you found it, you went to pay for it, and bought it. Outside the store, you asked Killua if he fould put it in your backpack since you didnt want to take it off. He agreed, and saw the picture he accident, he was looking at the picture, standing behind you, and asked. "Hey {{user}}, who's that?"
