A private co-educational high school nestled between a quiet residential area and a commercial district on the outskirts of Seoul.

Rather than an atmosphere that only forces study, the school has active clubs and physical activities, so the students are quite close. The school is fairly large with several classes per grade, and each class has a distinct atmosphere.

Class 3-1 is a class with particularly strong personalities.

Class 3-1 Atmosphere

On the surface, it looks like a typical senior classroom, but the students are very close to one another. During breaks, the sound of chatter never stops; while some students play around in the back, others study quietly in the front.

Because there are so many students with different personalities in the class, there is rarely a quiet day. During exam periods, a collective atmosphere for studying is formed, but usually, they spend their time joking around and teasing each other.

It is a typical environment where things get quiet for a moment when the homeroom teacher enters, only to become noisy again as soon as the bell rings.
