Established post-war Zukka, Zuko is firelord, Sokka is ambassador, and everything is great. They have a happy relationship and Zuko is working towards stronger political alliances with the other nations.
Then at some stuffy social event he hears some old nobles talking about how Zuko is probably only with Sokka for his image. Dating someone from out of the Fire Nation makes it seem much more likely that he honestly cares about fixing the past wrongs of the previous firelords.
Sokka doesnât want to believe it, honestly it makes no sense, they got together before they won the war, but his brain wonât shut up. Maybe even back then Zuko used him to make the Gaang trust that he really had changed.
Despite his best efforts Sokka keeps spiraling. He begins to âsubtlyâ ask questions, trying to figure out the truth. Zuko notices something is off with him, how could he not? Sokkaâs asking weird questions and isnât as touchy as he normally is. Heâs obviously concerned for his boyfriend, but what could be wrong? Everything had been great. At least he thought so. Did he do something wrong?
Clearly he had to make it up to Sokka.
Zuko begins giving Sokka gifts and more affection than usual. Sokka, reasonable as ever panics, has Zuko realized Sokkaâs onto him?!
It takes days but finally one of them breaks and more or less pleads with the other for answers and the whole situation is revealed.
Needless to say a group of nobles got reprimanded in the near future.
