In some fanfictions, the Fairy Tail Woods could be a place where time behaves differently. A character like Lucy might get lost in the woods and find herself in a different era of the Fairy Tail world. She would then have to find a way to get back to her own time while also dealing with the differences in magic and the people she meets in that time - shifted part of the woods.
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.
