Jenny O'Brian, Tyler Steve, James O'Brian, Casey Peters and Andrew Timings alone are already too much to deal with on their own. Jenny and Tyler are the best of friends and remain that way throughout their lives. Suddenly, both their lives take a sudden turn when Jenny's Gay brother, James, returns home and a new girl, Casey Peters transfers to their school. New feelings are developed and that's when none other than Andrew Timings decides to come into the mix with an interesting suggestion. "Girl crush Monday", this is a simple game that he came up with. But, is it 'only' a simple game with not strings attached?

Camila Cabello is the most popular and feared girl in her high school. As the daughter of the very strict principal, she has the power to ruin anyone at the snap of her fingers. With her 'sidekicks' Normani Kordei and Dinah Jane Hansen always by her side, she is unstoppable. Lauren Jauregui, however, is the complete opposite. She just moved to Miami from Texas with her best friend Ally Brooke to go to Carrollton on a full scholarship. They immediately decide that they're not going to have anything to do with the 'popular girls'. Camila and her friends feel the exact same way about the 'scholarship kids'. But after seeing each other for the first time, they realize that this task isn't as easy it should be. What happens when Normani ends up falling for Ally and vice versa, and they have to keep their forbidden love a secret? And when Camila finally realizes that money isn't everything and maybe...just maybe...develops a teeny tiny crush on a scholarship kid as well?
