OKAY guys I need help. This is to those of you who read Zukaang fanfictions. I once read this one-shot about the ship, it was really good, but I forgot to save it. I just thought of it today and have spent the entire day searching to no avail. I know this might be useless but considering how few Zukaang fanfictions there are, I hope this will work. So it was in a one-shot book dedicated to Zukaang. It was also a song fic based on the song Symphony. There should have been another part but the one-shot book was left unfinished. In the one-shot, Aang and Zuko sing a duet of the song while Aang plays the piano. There are bother either in high school or university and it's definitely an AU. I'm not sure why I'm so obsessed with this rn but if anyone knows what I'm talking about please let me know.
