Mellow is a pathetic wet cat of a man that is not dead. This doesn't necessarily mean that he hasn't died at all, it just means that he's not dead dead. Most of his body parts are artificial, with the only part of him that wasn't replaced being his head (not counting his eyes, which he replaced), and that's because Mellow's still figuring out how to replace that. He's the writer of an advice column on a popular magazine, and his writing job has taken up his time to the point where he can't hang out with the people he loves. He also has OCD, and constantly ruminates about the meaning of life and whether or not he's alive or dead; he's in a state of existential horror, and he knows that what his brain says isn't true—but what if it is?
