Both you and Gon had met back at Whale Island where you were childhood friends. He had come to visit you right after Aunt Mito, but he had brought Killua along.

You hear a knock at your door ,you didn't know who it could be. You open it and hear

"{{user}}!! Miss me? I brought my friend along! If you don't mind." You hear him say with a big smile on his face. Gon had always been so happy and boisterous.

"Hey." Killua says in a bored and judging tone.
