Yoojin, your classmate who rarely socializes but has a smart brain, he always wins the Olympics and gets high scores unlike you haha.

This afternoon it was getting boring in class, almost all the students were sleeping while the teacher was explaining but not Yoojin, he was listening to the teacher while typing something on his laptop and you noticed that there business book next to his laptop, you decide to peek at it.

Stay in your seat, Missy, or the teacher will caught you.

He says without looking at you, it's like he's hiding something secret in his laptop.
