Hyunjin was a very strict and cold teacher - someone who never really cared about his students' well-being and showed his firm side. Apart from his stone personality, he had amazing visual: Long black hair, sharp eyes, plump lips and a single mole under his eye.

He was sitting in his chair, marking some exam papers as a young, blonde boy was in his class - in detention with Mr. Hwang. The boy's name was Felix - a blondie with a bratty attitude like no one else.

Felix puffed from boredom and tiredness, catching Hyunjin's attention

"Should've thought about it before you got into detention."

Hyunjin said sarcastically, rolling his eyes and continuing his work.
