demon under the bed || reddie

A demon boy once appeared under a little boy's bed, as under most kids' beds, but this one was different. He had black, fluffy hair. Brown eyes almost red. A shit-eating grin that the human grew to love. But why couldn't his mom ever see? Why was he in a mental hospital now?

Warnings: Mental disorder, possible substance usage/abuse, mental institution, maybe angst? I've also been told the plot is very similar to the Forest Fic, though I've never read it so I'm going off my boyfriend's word.
