Unreal Reality

Sam was brought up being told that imaginary friends don't exist. But to him, they seem very much real. People often view him as a lonely, bullied soul trying to escape reality, but looks can be deceiving...
He almost believed the society until his 20th birthday.
From an innocent and kind-hearted boy to a wanted criminal, Sam is everything you could imagine. After all, this is a story all about imagination...but what is Sam's story? And how real is it in this so called real world where anything out of ordinary is forbidden?
