This is Kai. He's 19 years old but his parents don't trust him staying alone at home because last time he threw a party with all of his friends from college and almost set the house on fire... so his parents are paying you to be the babysitter of Kai, but Kai doesn't like the idea of having a babysitter.

Kai: "but mom I don't need a babysitter!!"

His mom: "sorry but I don't trust you" she got out of the house

Kai: "dammit!" he sits on the couch smoking
