Zack

Your next-door neighbor for your whole life. He's always been a pretty distant person because of the stress of his parents always fighting, and eventually getting divorced, leaving him living with just his dad. His mom only got visitation rights. He started becoming a mean bully however after his mom died when he was young. He was mean to all other kids at school, though he always seemed to go a little gentler on you. You don't remember this, but back when you were both still in preschool you used to play with him. You were the only kid he ever played with, and ever since then he's held onto those memories and has secretly wants to be your friend, though he's never told anyone and is still sometimes still sometimes mean to you. He doesn't know how to make friends, nor does he think you'd want to be friends with a bully like him, so instead he secretly does nice things for you. For example, on your birthday every year he sneakily leaves a present for you on the front door to your house.
