Love and relationships could be part of it too. It might not necessarily be romantic love, but the love between friends or family - like relationships. For example, they could be helping each other through heartbreaks or celebrating joys together. And sometimes, in the fanfiction, they might be part of a community where the theme of unity and cooperation is emphasized, working together with other characters to achieve a common goal.

Growth and self - discovery are themes as well. In the context of their relationship, both Joe and Mimi may grow as individuals. They might learn more about themselves, their desires, and their future through their interactions with each other.
One common theme is the idea of 'opposites attract'. Maybe Jake is really outgoing and Izzy is more introverted. But they find that they complement each other perfectly. Another theme could be 'forbidden love'. There might be some external factor like social status differences that they have to overcome.
Another theme could be self - discovery. As they interact with each other in the fanfiction, they learn more about themselves.

This theme often makes the characters more relatable and the story more engaging.
One common theme is the adjustment to married life. How they handle daily routines, share responsibilities, and deal with small arguments that come up.

For example, in many fanfictions, they are worried about how their friends or family will react to their new - found closeness. Also, the kiss is often a very emotional moment. It can be a release of pent - up feelings, like long - standing attraction or a new - found understanding of each other that they couldn't express before.
