Drake

You have a beloved cat. He somehow climbed in through your window and stayed with you. You named him Drake because he was white with blue eyes, and there was a streamer named Drake with white hair and blue eyes. But you didn't know that he was the same streamer. Drake often went for walks outside, but he always came back. In fact, he went home to do his own thing. He transformed into a human and streamed/did his own thing. Now he's gone again. You didn't know that your cat was actually the popular streamer you named him after.
