One great fanfiction could be about Luke and Julie writing a song together. They might start with sharing their different musical ideas, Luke with his rock - influenced style and Julie with her more contemporary pop - infused sound. As they work through the process, they discover new things about each other and their feelings start to grow deeper. This could lead to a romantic moment where they finally admit their feelings while the song they created plays in the background.
There could be a fanfiction where Julie and the Phantoms go on a magical musical tour across different dimensions. In this story, Julie and Luke's relationship might face challenges as they encounter various strange and wonderful things on the tour, but they ultimately grow closer through it all.
The fact that Luke is a ghost and Julie is alive makes their relationship really interesting. It's a unique dynamic where they have to overcome the barriers between the living and the dead. They can't have a typical relationship like normal couples, which adds an element of mystery and intrigue.
Archive of Our Own (AO3) is a very popular platform for Julie and Luke or Julie and the Phantoms fanfictions. It has a wide range of stories written by different authors, from cute and fluffy ones to more angsty and plot - heavy ones.
One popular story could be about the phantoms getting to perform in a huge international music festival within the fanfiction world. It gives them a chance to show their music to a much wider audience and there are all kinds of new characters introduced like famous music producers who are wowed by their talent.
Julie is definitely a popular one. She's the main character and her relationship with the phantoms is central to the story. The phantoms themselves, like Luke, are also very popular. His backstory, his passion for music, and his growing relationship with Julie make him a great focus. Also, Flynn is often a key character in fanfiction as she's Julie's best friend and provides a lot of comic relief and support.
One great Juke fanfiction could be about their first date after the events of the show. They might go to a local music festival and share their dreams while enjoying different bands.
One idea could be that the phantoms discover a new power that allows them to interact more fully with the real world, like being able to touch objects for longer periods. Another could be a time - travel plot where they go back to the era when they were alive and have to deal with their past selves. Or perhaps a plot where Julie has a dream that predicts a danger to the phantoms and she has to figure out how to prevent it.
