"Raise your hand if you know the answer children, it's not that hard. I can't stand in front of here all alone just talking for the rest of the day!" Mr.Yun exclaimed throwing his hands in the air with frustration.

"Psssssst....jungkook!" You whisper hissed to the guy in front of you. He ignored you, pretending to listen to Mr.Yun while really drawing doodles in his notebook.

"Kookie.....psssssssssst......Kookie!" You hissed again poking his neck with your pen.

When Mr.Yun faced the board Jungkook turned around, stoping you from almost poking his eye out.

"Stop it!~y/n what do you want?!" He asked with an annoyed face.

You pouted and hid behind your textbook. "Fine go back and listen to Mr.Yun or your doodles since their more important then me..," you whispered, looking up and quickly writing down a few notes from on the board.

Jungkook pulled your textbook down so it lay flat on your desk. "Y/n don't act like this, it's morning and I'm tired. What do you want?" He asked rolling his eyes and pulling on a piece of your hair.

"Shhhh...I'm doodling, can't you see I'm busy?" You mockingly replied drawing random squiggles in the corner of your paper.

He huffed and turned around, he picked up his pencil as if about to draw, but then put it back down a second later. He rested his head on his arms, closing his eyes.

You peeked up at him, he didn't go to sleep last night because of practice. Even if you told him not to the night before, he obviously didn't listen. Their debut song was coming out, No More Dream, and they were practicing like crazy.

"Jungkoooooooooookkkkkk," you said in a sweet voice.

He lifted his head up but didn't reply, drumming the pencil on his desk. You sighed and ripped a piece of paper out of your notebook. In red pen you wrote:

Kookie stop looking so sad. I was just joking~also sleep more tonight, I get worried sometimes

You folded the paper, and when Mr.Yun was busy with a math problem, you tossed the note on his desk. He stared at it for a few seconds, then unfolded it and read the note inside. While a small smile was tugging at the corner of his lips, he picked up his pencil and scratched out a reply:

Your worse then my mom, if you sleep early instead of studying for exams then I'll sleep early~stop working about me so much y/n! :)

He folded the note and tossed it back over his shoulder, pretending to be focused on the board. You read what was inside and shook your head, a smile on your face. You picked your purple pen this time and hurriedly wrote your reply down, throwing it at him so you could copy what example Mr.Yun was giving that would be on the Exam.

I'm your best friend, it's my job to worry you idiot, not yours~did you finish practice or do you need to do more vocal recording?

He smirked and looked back shaking his head no and mouthing 'I'm done, thankfully.' You made a relived face and shot him a thumbs up, he smiled and stuck his tongue teasingly out at you in reply.

"JUNGKOOK, turn around and stop flirting with y/n!" Mr. Yun called out at him, pointing at the math problem.

You giggled as he snuck lower in his seat, his face heating up. "Yes Sir..," he mumbled covering his face with his textbook.

"If you like talking so much then come up here and do this math problem," Mr.Yun said grinning as Jungkook gulped.

You tried not to laugh at his misfortune, he had to do math? This was not going to end well...
