More than anything, she's afraid that if people really knew her, her whole world might fall apart.

Marianly Tejada as Bronwyn
Actress Marianly has starred in a number of roles, including in Orange Is The New Black and The Purge, and in this new series, she'll play Bronwyn.

Barrett Carnahan as Jake
Barrett, who began his acting career with roles in the series Grey's Anatomy, Drop Dead Diva and Modern Family will play Jake.
As the captain of the football team and the boyfriend of Addy, Jake seems to have it all, but it’s never enough.
Mark McKenna as Simon
Mark is an Irish actor, musician, and singer, and is mostly known for having starred in Sing Street and Wayne. In this series, he will play 'The Outcast' Simon.
Simon is a brainy outcast and the creator of a gossip app that holds the entire school captive - kind of like Gossip Girl. His posts are juicy, snarky, cruel, and most importantly: always true.
He takes pride in exposing his classmates as the "liars and hypocrites they really are." Even though all of his classmates read his app, they also all hate him for it.
Melissa Collazo as Maeve
21-year-old actress Melissa recently starred in Swamp Thing and Lena And Snowball, and she'll be taking on the new role as Maeve in One of Us Is Lying.
