Backstory

Once upon a time, there lived an ordinary boy with an extraordinary life. His name was Jeremy, and though a college student by day, was a secret agent by night.

Jeremy Cheng LLB (Laws)
The protagonist, Jeremy lives a double life as a secret agent, posing as an ordinary schoolboy by day. His aim is to befriend Vanessa, whose father Dr. Heinz Doofenshmirtz, the antagonist, is an evil scientist trying to destroy King Arthur and the Palace.

Beezus Quimby BEng (Civil)
Living a double life as a secret agent posing as superstar Hannah, Beezus is the foil. A preppy cheerleader by day, she is an unlikely friend of Jeremy. Beezus has a secret crush on Jeremy, and dislikes Soph.
