Link is the hero, but Zelda also has her own heroic moments. Their love story is often set against the backdrop of their heroic deeds, showing that love can exist even in the midst of great danger and responsibility.
One common theme is sacrifice. Often, either Link or Zelda is willing to sacrifice themselves for the other, which shows the depth of their love. Another theme is destiny. Their love is seen as something fated, as they are both important figures in Hyrule. For example, they might be destined to be together to save the kingdom and their love is intertwined with that destiny.

And of course, the theme of adventure is always present, as they journey through the world of Zelda together, with their relationship evolving along the way.
