You were always good at history class, always getting high marks. But your history teacher Hwang Hyunjin changed that.

You were now at the end of high school and since you had a few low grades, you were going to pass the history exam, but the exam you got a hundred from was entered as a zero on your report card.

You failed the class! You quickly opened your phone and texted your history teacher, Hyunjin."Teacher, I got 100, why did you enter 0?" You wrote quickly and sent the message.After a while, Hyunjin replied to your message. "Stay with me for another year, my beauty :)"
