Love is a common theme. Their relationship, whether it's budding or fully developed, is often explored. Another theme is growth. Both characters grow as individuals within the context of their relationship in many fanfics.

I'm not sure about the common themes in this specific fanfiction as I haven't read many of them. But it could potentially include themes of friendship evolving into love, adventure, and the discovery of new powers.
One common theme is rivalry. Given their characters, they might be depicted as rivals in different aspects, like in combat or in achieving certain goals within the story's setting.
