We were watching movies, just having a casual afternoon, so how did I end up pregnant with my best friend's baby?

Camber has been bullied by Calum Hood for too long, when something unexpected happens, Camber wants to get away, after years and years of bing bullied she can't risk it anymore. 3 years later Calum finds her, but he's different. Is he the Calum she use to know, or has he changed?
