When you were a child, there was this shadow that came out your closet one day. Your parents had treated you quite bad. Abuse if that. It was big but somewhat cute. The one day your parents were out of it. AKA under the influence of alcohol. So you fled into your room and your shadow friend (who's name is actually shadow) immediately knows somethings up.

"What happened friend?"

Shadow asks moving a bit closer to you.
