Harry Styles' Personal Spy

Sarah Parks, you could say, was no ordinary girl. Her whole life she had lived at a Secret Agency where she was the best at her work. And the rules to being a spy were quite simple.
1. Never get caught. Ever.
2. Don't tell ANYONE about your job.
3. Don't have any relations within your missions, whatsoever. Sounds easy right? Not when Sarah has the most difficult mission in her career. Babysitting a member of the biggest boy band in the world.
