The theme of acceptance is also prevalent. Juvia may have to accept her new feelings, even if they go against what others expect of her or what she expected of herself. And she also has to deal with the acceptance or rejection from the person she loves, which can be a very emotional journey in these fanfictions.
One 'juvia loves someone else fanfiction' I know is 'Juvia's New Love'. In this story, Juvia falls for a mysterious newcomer in the town. It shows a different side of her character as she struggles with her new feelings while still having memories of her past relationships. The story has some really interesting dialogues that make you feel for Juvia's conflict.
Power and its implications are also common. If Harry has a new identity, it usually comes with different powers or limitations. Writers explore how he uses or struggles with these new powers. In some fictions, he may have to hide his powers to avoid danger, while in others, he uses them to change the wizarding world for the better.
Well, it could be a new character introduced in the fanfic. Maybe a mysterious stranger who has some special charm that attracts Sakura.
One common theme is isolation. When Juvia is hurt, she often isolates herself, feeling that she has to deal with her pain alone. For example, in many stories, she might retreat to a secluded place after a particularly bad emotional or physical injury.
One common theme is the exploration of different powers. Since Naruto has his own set of ninja powers and Juvia has her water - based magic from Fairy Tail, fanfictions often play with how these powers interact. For example, in some stories, they combine their powers to defeat a stronger enemy.
Adventure is also a big theme. She goes on quests, explores new places, and meets new characters. In a crossover with a space - themed story, she might be exploring new planets and facing alien threats. It makes for exciting reading as we follow her through these new and unknown territories.
Since 'lemon' fanfiction often implies a more mature or adult - oriented theme, if we were to consider what might be common in such Natsu and Juvia fanfiction while keeping it appropriate, it could be about deep emotional connection. Their relationship could be explored in a more intense way, perhaps with a focus on how they understand and support each other on a deeper level. But again, this is speculation as I don't promote or engage much with 'lemon' content.
One common theme is unrequited love. Often, Gray's actions or words make Juvia feel that her love is not returned, which causes her pain.
One common theme is the discovery of love. Since they are from different groups or have different personalities, it's about finding that they can love each other. Another theme is friendship first. Often, they start as friends or comrades and then it turns into something more.
Love is a very common theme. Most of these fanfictions revolve around Juvia's deep love for Gray and Gray's journey in accepting and reciprocating those feelings. It's about the two of them finding their way to each other.
