Sokka and Katara acted like actual siblings, but Azula and Zuko’s relationship wasn’t even that of the favorite and unfavorite sibling. Azula was just a tormentor, and there was so little familiarity and warmth that one would be hard pressed to think they grew together. Plus, Azula puts on this Seductress demeanor when she’s toying with someone, that gives everything this bizarre sexual tinge. Even the way she says her pet name for Zuko, “Zuzu”, makes her sound more like an Ex than his sister.
That, Plus the fact that Zuko is one person who, despite everything she is and has done, especially to him, still tries to support and rebuild the bridges with her that shes burned. That sort of things makes sappy romantics quiver.
