As the characters develop in the fanfictions, they grow both individually and in their relationship, like Natsu becoming more understanding of Lisanna's feelings and Lisanna becoming stronger to stand by Natsu.
One common theme is the adjustment to married life. In the world of Fairy Tail, they have their own adventures and responsibilities. So, in these fanfictions, they often have to figure out how to balance their married life with their duties as mages. Also, the theme of growth is there.

Also, themes of courage and finally expressing hidden feelings are common.

Lisanna might face a lot of backlash from the guild. Her friends could be disappointed in her and might not trust her as much. She could lose her standing in the guild and have to work hard to regain people's respect.
Well, in many fanfictions, Natsu might initially be in shock. He's a passionate character, so he could react with anger. He might lash out at Lisanna or the person she cheated with. He could also go into a state of self - doubt, wondering what he did wrong.
Well, in many of these fanfictions, the theme of magical discovery together is quite popular. They both are mages in Fairy Tail, so authors like to write about them finding new spells or magical artifacts while also strengthening their bond. And then there's the theme of protecting each other. Natsu is a very protective character, and in fanfictions with Lisanna, this trait is often emphasized as he defends her from various threats. Lastly, the theme of family acceptance can be seen. Since the Fairy Tail guild is like a family, fanfictions might explore how the other guild members react to their relationship and how Natsu and Lisanna deal with it.
