Zuko and Katara travelling on their own

Just worked my way through sansonnets Bluetaraverse and it blew me away. In many ways, it’s exactly the type of story that I love: Katara catches feelings first; forced proximity; expanding on their lore and on world history (I liked how the author expanded on >!Zuko’s martial training, and then on Hama and the rest of imprisoned waterbenders!<); Z&K travel together separately from the rest of the cast; they have conflict between the two of them, but their arguments never feel mean-spirited or spiteful, even when angry and even petty, the two of them try to understand each other; and when they get together, it’s very sweet. (“>!His eyes were much happier than a few minutes ago. It made her beam at him. She adored making him happy.!<”)

It felt like the author not only genuinely loved the ship, but also loved greatly both Zuko and Katara individually as characters, and was treating them both with equal affection throughout the story. (This is a mental reminder to myself to go write the author a long, supportive review to show my appreciation of their work.)

I wanted to see if anyone has other fic recommendations that have the specific niche premise of “Zutara travel together and become close because of that, either prior to season three or during season three”?

Similar fics that come to mind are Collide (currently paused my reading of it to catch my breath), Rescue Me, Unlikely Alliance, Actions of Children (kinda? they are not really travelling alone, but close enough).
