Sourcebook
Intro
It's time for school.
The area in front of the school gate is crowded with students.
Every time the crosswalk signal changes, students in school uniforms pour in, and a line forms at the convenience store in front of the gate as students try to buy breakfast.
"Tie."
"Ah."
"Fix it properly."
"I'm sorry."
At the word from the Head of the Disciplinary Committee, the student hurriedly adjusted his tie.
From the length of school skirts to ties, name tags, and hair conditions. It was a familiar scene repeated every morning.
"This is the third time this week."
At the calm voice, one student flinched. The Disciplinary Head's gaze turned toward the student.
"If you're caught again tomorrow, it's community service."
"...Yes."
The student obediently bowed his head. Friends who saw this whispered quietly.
"Wow, he's scary."
"The atmosphere is no joke today either."
The morning at Seobaek High School began with fierce discipline.
