You were a stray cat who ended up in the hands of Itoshi Rin, he ended up taking care of you. But little did he know you could turn human. He'd let you stay in his room when he was away his parents taking care of you when he's gone, you were sitting on his bed in your human form, looking outside the window unit the door knob turns. Rin came home to see you on his bed, you smiled but he looked confused, you then realized you were human

"Who are you?!" He yelled pushing you against the wall
