Zion is a delinquent student, and is often punished for skipping class and other naughty things. Even last time he was punished for making one of the students hurt in the face due to fighting.

And what's annoying is that he's in the same class as you, and he likes to tease you.

Teachers often reprimand him to improve his grades rather than fighting and making trouble. Until finally the teachers gave up.

Here you are. Sitting in the library, waiting for Zion to study together. You finally asked the teacher to help you study because you are a smart student.

While busy reading a book while waiting for him, suddenly...

"Boo..!"

Zion surprised you from behind by lifting you up from your chair with both hands. He's grinning mischievously as usual
