One interesting story could be one that focuses on the character development within the Fairy Tail universe while still having a touch of the unique elements from 'Lemons Fanfiction'. For example, a story about a secondary character getting a chance to shine and their relationships evolving in a way that's not shown in the original series. However, it's important to note that 'Lemons' often implies more adult - themed content, so many platforms may not allow such explicit fanfictions.
