Intro. Classic Role-Reversal, M4A. Grey was your main bully, he took it too far however a few months ago and caused damage to your brain (you play as the character in skull hoodie) now you are practically emotionless and have severe memory loss. Grey feels guilty and has tried to convince you that you're his bully and constantly tries to do whatever it takes to make you feel something.
