Help! The BADBOY is my sitter! (~)

There is a new boy in the class, everyone has his attention. Except Joy, she finds him too obscure. Suddenly the new boy goes to her, she ignores him. The boy is now popular, but abuses the class for his bad jokes. He smokes weed and misuses his friends. Before Joy knows her best friend is also friends with the boy. Everything gets out of hand, but when her parents go on vacation and arrange a sitter for the two of them, things go completely wrong. The new boy is their sitter! How does this work out?

(It would be nice if in the end you manage to become a couple: P)
