Well, in some fanfictions, it could be through a dangerous situation. Maybe Lucy is in peril and Natsu's intense fear of losing her makes him realize his love. For example, if she's captured by a powerful enemy, Natsu's desperation to save her and the way his heart races at the thought of her being hurt could be the trigger.
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.

In fanfiction, this could be a really interesting development.

It could also be due to some shared experiences within the fictional scenarios created by the fanfic writer.
The theme of unrequited love can also be common in some 'lucy loves natsu fanfiction'.

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 possible plotline is that Natsu starts writing in the diary about his confusion regarding his feelings for Lucy. He might write about how he gets jealous when other guys show interest in her. Another plot could be that Lucy accidentally discovers the diary and confronts Natsu about it, which then leads to them finally admitting their feelings for each other.
The chemistry between Natsu and Lucy is full of potential for interesting stories. In fanfiction, authors can take that chemistry and develop it in different ways, like exploring what if Natsu realizes his love in a different situation.

It could also add a new dynamic to the Fairy Tail group as a whole.
