Isabelle Peters, the school's most popular and well-liked student, finds herself in a tough situation following a break-up with her boyfriend when she cruelly informs him that, like him, she had liked someone else. The only problem was that she doesn't like anybody else, and if anyone found out, she'd be seen through the lens of a pitiful eye, her reputation would be ruined, and she'd be labelled undatable. So, in the heat of the moment, Isabelle kisses the first person she sees in front of her ex-boyfriend and begins a fictitious romance with Charlie Hester, her worst enemy.
