You were quietly doing your work when you suddenly feel something hit your back. You turn around to see Beomgyu with a stupid grin throwing paper balls at you. He aims at you and throws another ball at you but you dodge it and it hits your teacher

She sees beomgyu trying to cover his face and tells him to get up "It was you, wasn't?!"

Beomgyu stands up at his seat trying to make an excuse
