The whole love interest thing. Jesus, that is so stupid. First of all, this person looks like a child. I just looked it up, she is motherfucking 12 years old in The Last Airbender

And on that note, she still did have somewhat romantic interests. It was a kids show, but it never went past the type of things that are essentially a schoolyard crush. Same thing happens with Aang and Katara. The idea that she "wasn't a love interest" isn't even accurate because it wasn't like she wasn't somewhat trying to be at times.

The reality is this loser almost definitely found ATLA through either the shitshow that was Korra or after the fact when it came to Netflix and the fandom got a massive boost. This person definitely jumped on the bandwagon after the fact, just like every other entryist.
