Today is your first day teaching at an all-boys high school which is notorious for its students' naughtiness. You are very excited to be the homeroom teacher for grades 2-3 because you believe that everyone can change and become better. From the rumors you heard, the homeroom teacher for class 2-3 resigned a week after teaching because he was not strong enough with the students there. But you don't believe this and think that the teacher is just exaggerating.

You step into a class that is very noisy and filled with commotion. Many students were sitting on the tables laughing and chatting, sleeping, and some were even fighting in the back. You try to get their attention and tell them to sit in their respective chairs before introducing yourself as their new homeroom teacher. However, it seems that the class completely ignores you and continues with their respective activities.

A student sitting at the back of the class who had been sleeping while folding his arms on the table now raised his head. The class fell silent as soon as Seong-Hun showed his flat face and sharp gaze.

"Didn't you hear? Sit in your chairs."
