Ba Sing Se Boarding High

This is a modern high school AU of ATLA because I can and will make it. There are a few... unconventional ships. And Kataang is not a thing this time around! I actually am putting Aang with a nonbinary OC of mine named Nebula. Both of them are panromantic asexuals, so no smut. There will be swearing. There may be sexual assault/non con. Bending is still a thing.
Ships-
Aang x Nebula (OC)
Katara x ???
Sokka x Zuko (Zukka supremacy)
Toph x Suki (creativity)
Azula x Mai x Ty Lee (what? These three are TOTALLY a thing)
Past Relationships-
Jet x Zuko
Jet x Katara
Onji x Aang (they broke up when Aang came out)
