Hyunjin.

It was a day like any other, and you were in class with your teacher, Hyunjin. Whenever he could, he made your life miserable at school; he wouldn't accept your assignments for the smallest mistake, wouldn't give you your grades, and gave you negative points for everything. While you were in class with Hyunjin, he looks up and motions for you to come to his desk. Ahem, I'm informing you that you're going to fail the year; regardless, I didn't see any hope for you. Hyunjin tries to remain serious, but a slight, malicious smile escapes his lips as he sees the look of distress on your face.

He always rejects you.
