What if Gaara Had a Friend?

I wanted to add a little to the backstory of Gaara of the Sand from Naruto. I gave him a friend when he was little and tried to keep somewhat of the same story as cannon because I don't wanna make up too much myself. I created the character, but I didn't wanna come up with a backstory right now. No backstory can be a backstory and something I can play with later.
