New friend

(Modern au)
Bender high. Place to learn and work on your bending. Airbenders sadly are all dead. Aang is the avatar and no one knows, not even his best friends.
Due to waterbending being the closest to airbending, he pretends to be a water bender.
What will Aang do when someone pops up in his life? Someone who went through pain just like Aang.
Will they turn into friends? Despite the gaang, except toph, not liking him? Or will they be pushed away?
