If we think about more underrated actors, Florence Pugh could be amazing as Brittany. She has shown her range in various roles. And for Alex, we could consider Asa Butterfield. He has grown as an actor and could bring the right energy and vulnerability to the role of Alex.
Maybe Saoirse Ronan for Brittany. She's a very talented actress who can portray strong and complex female characters. And for Alex, Ansel Elgort could be a possibility. He has the looks and the acting skills to play a character like Alex, especially if the character has a bit of a rebellious side.
One plot idea could be that Brittany and Alex are in a small town and they discover a hidden treasure map. They then embark on an adventure together, facing various challenges and growing closer as they search for the treasure. Along the way, they might have to outwit some local villains who also want the treasure.
I really like the 'alex and brittany fanfic' where they are in a fantasy world. They have to work together to defeat a magical foe, and through that adventure, their bond deepens. It has great world - building and character development.
Don't forget about the details. Describe their surroundings, what they wear, how they talk. If they are having an argument, show their body language and facial expressions. This will make your 'alex and brittany fanfic' more vivid and engaging for readers.

The Chipettes are Alvinette, Simonette, and Theodoreette. Alvinette is likely to be the more adventurous and mischievous one, similar to Alvin in the original Chipmunks. Simonette would be the smart and logical one, while Theodoreette is the sweet and gentle character.
A magical detective who is investigating some strange magical occurrences in the neighborhood that Alex gets involved in. This character could be really serious and by - the - book, which would contrast with Alex's more carefree nature.
