Mako x Male avatar reader

I know it sounds weird but what I'm gonna do with this is going to be interesting I swear, you are a previous test subject that is sent into the past, you, as the title says, are an avatar, but you don't take Korras place. You are naturally an earth bender, not the one right after Korra but from the next cycle. You're scared and don't understand what happened, but someone you find becomes closer that you would think.
