One of the common themes is the exploration of their unique bond. Given their different backgrounds in the original story, fanfiction often dives deeper into how they bridge that gap.

As they are in a relationship, they discover new sides of themselves. For example, Renton might find a new sense of courage because of his love for Eureka, and Eureka might discover more about her humanity through her relationship with Renton.
