I don't know, to be honest. It could be an original story that just shares some common themes or tropes with other works, but not directly a fanfic of something specific.
Red White and Royal Blue is not a fanfic-based story. The plot and characters were developed independently by the writer without drawing from any existing fan-created content. It stands on its own as an original piece of fiction.
Red White and Royal Blue is not a fanfic. It was independently created and published as a standalone novel. The story and characters were developed specifically for this book and not derived from any existing fan-created content.
Yes, 'Red White and Royal Blue' started out as fanfiction. Fanfiction writers take existing universes or characters and create their own stories. This particular work, which grew out of that fan - based creative space, has since become a well - known story in its own right. It has been able to build on the initial fan - created ideas and expand into a full - fledged novel and subsequent adaptations. The fact that it began as fanfiction also means it has a unique origin story compared to works that are created entirely independently.
Another common theme is self - discovery. The characters in the 'red white and royal blue' universe are often on a journey of finding out more about themselves. Fanfics explore this in different ways, like how their relationship with each other helps them to understand their own identities better.
One idea could be a fanfic that explores what happens after the events of the book or movie, like their lives as a married couple dealing with international relations. Another could be a prequel fanfic focusing on their first secret meetings and how their feelings developed from dislike to love.
