The theme of redemption can also be present. If a character has made mistakes in the past, like Lyon perhaps in his rivalry with Gray, the fanfic might explore his journey of redemption. Juvia could be the catalyst for this change as she has a big heart and might encourage him to be a better person. And Gray, on the other hand, could be dealing with his own demons, like his past with Ur, and through his interactions with Lyon and Juvia, he finds a way to move forward and heal.
One common theme is the exploration of love that defies expectations. Since Juvia was initially interested in Gray and Lyon has his own goals, their coming together in fanfics often shows a love that surprises both them and the readers. Another theme is the power of friendship. As they interact, they also form a bond of friendship which then morphs into something more romantic.
Character development is a big part. For example, fanfics may show how Lyon's reserved nature and Gray's more outgoing side change over time due to their relationship. They could also involve elements of the world they are from, like the magic or the social structure, which affects their relationship.

There's also 'Lyon's Heart for Juvia' that focuses on Lyon's feelings for Juvia and how he overcomes obstacles to be with her.
Gray could be a great addition. Since Gray has a history with both Juvia and Lyon, his presence can add a lot of drama. For instance, his reaction to Juvia and Lyon getting closer could range from jealousy to acceptance, which would create different story arcs.
