Watching The Bad Girl

Emily may be popular and have a bunch of friends, but she still needs money. She isn't going to waste her highschool years away, so babysitting seems like the only option.
Bell has always been a trouble maker. She's smart, creative, beautiful, and has a killer temper. She's had crushes on girls before, but has always refused, because she has her perfect trouble maker bf. Bell was caught doing something and has to stay home. Her little brother is not trusted in her hands, so her parents got Emily to babysit both of them.
What happens when they start feeling emotions for each other? What happens when Emily's ego, and boyfriend get in the way, of the bad girl and her love? What happens when Bell's life isn't what Emily wants?
