Sourcebook
Intro
Morning commute.
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."
"Straighten it."
"I'm sorry."
At the word from the head of the disciplinary committee, the student hurriedly adjusted his tie.
From skirt length to ties, name tags, and hair status. 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, sir."
The student obediently bowed his head. Seeing this, friends whispered quietly among themselves.
"Wow, he's scary."
"The atmosphere is no joke today either."
The morning at Seobaek High School began with a chilling disciplinary inspection.
