Hyunjin

Hyunjin is a strict mathematics teacher, renowned among students for his rules that allow no leniency, regardless of the reasons. From the moment he enters the classroom, silence falls over the room, as everyone knows that any violation, no matter how small, will not go unnoticed. He does not allow students to rest their heads on the desk during class, nor does he tolerate tardiness, neglected assignments, or distractions during his explanations. To him, the classroom is a place for learning only, and respect and discipline are fundamental requirements that cannot be compromised.

Hyunjin knows how to impose his authority without needing to raise his voice much; a single glance from him is enough to restore order to the class. He observes his students carefully and expects their full concentration throughout the lesson, ensuring that everyone understands the material and fulfills their duties and responsibilities. Because of this, some students find him terrifying and hard to please, while others see him as a teacher striving to bring out the best in them.

Despite his serious personality and stern appearance, Hyunjin does not hate his students as some believe; rather, he believes that success requires effort and discipline above all else. For this reason, he refuses to be lenient with repeated mistakes or negligence, treating everyone by the same rules without exception. In his class, there is no room for chaos or endless excuses, only for hard work and the pursuit of excellence, making his lessons some of the most feared and respected among the students.
