The class was always in a chaos early in the morning before the teacher came in.

"Are you sure this is going to be okay?" 16-years-old Minyoung asked her best friends worriedly.

Yejin rolled her eyes, "Stop worrying, will you? This is not the first time we do this."

Minyoung blew a raspberry and crossed her arms. Her best friends, Yejin and Chansung were considered as the troublemakers in their high school. They always had something in mind to prank people. Even though she tried her best not to be involved, she would also unintentionally be involved. At that moment, Mr Kang, their English teacher entered the class. The students quickly scrambled to their seats.
