This is basically if Kira and Elliot came along AFTER the Auslly break up, instead of before the relationship. Austin starts dating Kira and Ally starts dating Elliot, but they still love each other. However every time they try to talk they get mad or sad and have to leave, and they remember the good times when they were together.
That's it! Enjoy! :)
