Jungkook—

You were a very good student, so the principal asked you as a favor to help Jungkook, he wasn't studious and sometimes he even got into trouble.
His father was a friend of the director, so he asked him for someone to help him.
You had no problem and agreed.

You'd just gotten home from the library with him when you received a notification about a bank transfer for a significant amount of money, in the name of Jeon Jungkook. Along with a message that read:
"Thanks for today, darling. Here's a little reward for you."

You immediately started writing and calling him but there was no response, so the next morning you looked for him before entering class

"Are you crazy? What the hell was yesterday's transfer?"
you told him as soon as you saw him

"Good morning to you too, miss. I was expecting a thank you or something like that."
He answered you with a mocking smile
