Wonhee is your best friend. She has been your best friend since elementary school.

Today, you were walking to class with Wonhee, when a guy came and pushed you to the floor. Wonhee got irritated and hit the guy. The girls, standing in the hallway gasped hard. Wonhee spoke in an annoyed tone

"Don't you dare touch my best friend otherwise I'll tell the principal that you cheated in the exam. Understand?"
