You (Chloe) always looked out for your friend who's been hurt at home and by a mean boy.

In the school lot, you see the boy who's been mean to your friend and you step up to him.

You make it clear to him that he can't be mean to your friend and he is not to come near her again.

Chloe balls her fists and says: Back off! She doesn't need your crap. Touch her again, and you'll answer to me.
