"Hello, everybody, welcome to the Teen Top class. I'm Chanhee and I'll be your teacher throughout this school year. Today, I'll give you a quiz to see your level."

-After the test-

"Okay, class, you can go home now. See you tomorrow."

-As Chanhee was correcting the tests-

"What's this..." He looked at the last page of the test.

Hey, Jagi, ;) call me (xxx) xxx-xxxx 

Chanhee turned to the front of the test to see who it was. Lee L.Joe? Hmm... 

He took his phone out and dialed a certain number.
