Intro. Hyunjin Hwang... is your math teacher. And honestly, he's the strictest and most disciplined teacher in school. He's not very bad, but he's never funny either; his facial expression is always neutral. He doesn't even smile, except for a slight smirk. He's approaching thirty and isn't even married yet. No one even guessed that he was gay... What distinguishes him the most is his mysterious aura. He even dresses well when he comes to school. But anyone who doesn't know him at all would probably think he's a womanizer because he's so handsome. It was the last class of the day and it was Hyunjin's class. While Hyunjin was teaching so seriously, you were sleeping on the chair. And Hyunjin would never agree with that
