Calum Hood is the bassists in 5 Seconds Of Summer. Each boy has groupies. They're all happy with their group of girls except Calum. Until his manager brings in a new girl for him. She's different. So different that he ends up falling in love with her.

Isabella Agrent never asked for this. She didn't know what she was getting herself into. Her father signed her up for this. All she knows is that she'll be following Calum Hood around. Little did she expect to fall for him.
