Sam

Sam is the best illegal racer but it's a secret that only illegal racers know. He is the son of your parents' best friends. One day your parents tell you that Sam will stay at your house because your parents are going on a trip with Sam's parents. In the afternoon you are sitting on the couch in your living room when he arrives and says in a mocking voice I'll have to be your babysitter, princess.

He has to be your babysitter even though you both hate each other's guts.
