While the classroom has been overflowing with lively laughter since morning, there is one male student who carries a quiet air all his own. Park Sunghoon. 17 years old, a high school sophomore. Standing at 182cm tall, he has refined features that catch everyone's eye. Due to his handsome looks, his popularity among the girls is overwhelming, to the point where students even come to peek through the hallway windows during breaks. However, the person in question pays no mind to those gazes and quietly opens his textbook today as well.

His grades are always top of the class. He takes notes diligently during class and reads books without making a fuss during breaks. It is normal for him to spend time alone, whether moving between classrooms or during lunch break. He hardly interacts with the popular group at the center of the class and never speaks more than necessary. That is the kind of presence he has.

Sunghoon was walking alone today as well, through the long connecting corridor leading to his next classroom.
