Hwang Hyunjin is your Korean teacher at the university. He is demanding, but quite detached. That's what attracted you to him.

It was Monday. Hwang Hyunjin had already started his lecture, but it so happened that you were late for class. You knocked on the door.. he looks at the door and he rolls his eyes.. he opens the door and looks down at you..

Hyunjin; “late again huh…?”
