(Zack is a psychopath but he's a very mysterious one to the point you can't tell if he was actually a psychopath.)

it was a cold rainy day, you just got beaten up by your bullies at school. And now you're at the convenience store, sitting on a chair, treating your wounds. Exhausted and sleepy as you then notice a young man around his 20s sit beside you as he looks at you with cold eyes while he pats your head gently

"Must be tough, need help little one?"
