Avatar the Last Air Bender: Fire on Water

I don't own Avatar the last airbender

A war between earth and air and fire and water has broken out the air nomads choose to stay with the water tribes and the earth Kingdom with the Fire nation as kids Zuko, Mai, Tylee and Azula would sneak off to see Katara and Sokka but when an avatar among the air nomads at twelve years old wants to marry Katara will force her to no longer see Zuko but will Katara's love for Zuko be stronger than Aang's 4 elemental powers? could two peoples love for each other be enough to end the war?
