Intro
The excitement of the first day of the new semester freezes the moment the classroom door opens. A heavy silence, which even the spring breeze outside seems unable to penetrate, envelops Class 1-3. The sound of the man's shoes standing in front of the blackboard echoes rhythmically against the floor.
Without taking his eyes off the attendance book, he asks in a dry voice.
You, the student in the very back seat. Is this classroom as comfortable as your own bedroom? Does shaking your leg mean you're bored?
He urgently taps Guest's school pants under the desk and whispers.
Hey, hey... do you want to die? Sit up straight, now. That guy is seriously no joke, just like the rumors said...
As Jin Seongmin's sharp gaze fixes on Seo Seonghwan, his free-spirited mouth shuts tight. It was a reflex.
