The theme of unrequited love can also be common in some 'lucy loves natsu fanfiction'. Maybe at the start, Natsu doesn't realize Lucy's feelings or is too focused on other things like his next adventure or his training. This creates a lot of tension and drama in the story, as Lucy tries to hide or express her feelings while Natsu is oblivious.
One common theme is the development of their relationship. Writers often explore how Natsu and Lucy's friendship gradually turns into something more romantic. For example, they might show how Natsu starts to notice the little things about Lucy that he didn't before.
One common theme is secrecy. Since it's about Lucy's diary, there's often an element of secrecy involved, like Natsu finding the diary by accident and having to keep it a secret. Another theme is the deepening of their relationship. As Natsu reads the diary, he gets to know Lucy on a deeper level, which brings them closer.
The theme of sacrifice also appears. Natsu might be willing to sacrifice his own well - being or goals for Lucy once he realizes his love. For instance, he could give up a dangerous but lucrative mission to stay and protect her. It's all about showing the depth of his new - found love.
One common theme is adventure. Since they are from the Fairy Tail guild which is all about going on quests, many fanfictions continue this trend. They go on new adventures together, facing powerful enemies and discovering new magic.

Since Natsu and Lucy have a great chemistry in the original series, in hotel fanfictions, the hotel setting often provides a more intimate and private space for their relationship to develop, like in 'A Romantic Hotel Retreat' where they finally confess their feelings in a cozy hotel room.
One common theme is the exploration of their unspoken feelings. Often, in the series, their relationship is somewhat ambiguous, and fanfiction allows for that to be explored more deeply with the kiss as a climax of those pent - up emotions.
Power and growth is another theme. As they face challenges together, they become stronger both magically and as individuals. Their relationship also strengthens during these times. They rely on each other's powers and learn to work in harmony, which is often explored in fanfictions.
One common theme is the journey of self - discovery. Natsu often realizes his love for Erza while on a journey or during a difficult task, which makes him understand his own emotions better.
One common theme is the development of their relationship from friendship to love. It often shows how Natsu starts to see Mirajane in a different light and how they gradually fall for each other.
