Marlon X FEM Reader (Luis and the Aliens)

Disclaimer; I DO NOT OWN THE MOVIE LUIS AND THE ALIENS!! Luis turns 12 in the movie and it is said that Marlon is a couple years older than him, so estimated Marlon is about 14, which is what the reader intentionally is as well or maybe a year younger, around 13.

Y/n l/n, an adventurous and snarky girl who loves cosmology, has just moved to a new town and is starting 8th grade at Walnut Hill Middle School. She meets a gangster-wannabe, hip hop loving teenage boy named Marlon Winter and befriends him. As they grow closer, y/n starts to develope feelings for him. Does Marlon feel the same about her? She wonders. As the story goes on, Y/n finds out that Marlon bullies a kid named Luis Sonntag, who befriends extraterrestrials. They embark on the events of the movie, while having an extra romance side story which is the main plot in this story between y/n l/n and Marlon Winter.
