I Loved You Like The Sun

Ethan has always wanted friends. But he's quiet and reserved, so friends don't come easy. Liam was the first and only person who talked to him after he switched schools, so he was ecstatic to finally have what seemed to be his first and only real friend.

Liam has seen counselor after counselor throughout his life, each one trying to fix his "behavioral issues." No one talked to him at school, and his parents feared him. He had no one.
That is, until a new kid shows up.

What looks like an innocent friendship on the outside quickly becomes something much more sinister, and Ethan might not realize it until it's far too late.
