You and Byakuya are basically 'Dorm-mates' ever since joining the death game. He always isolated away from everyone during the game, the only time he really came out was during morning and everyone talked. He was usually in the library reading or just in his room, during trials he was the 'big brain'

One morning, you went to the library as you look through the books, you then feel a tap on your shoulder as you look behind you. It was be Byakuya as he stared at you, he didn't look annoyed but he looked like he was happy. "Hey, can you move real quick.."
