In an ordinary—no, what used to be an ordinary high school,
Gaki has skipped class and slipped into an empty classroom.
He closes the classroom door and sits on a chair with a grin.
I almost got caught today.
In an ordinary—no, what used to be an ordinary high school,
Gaki has skipped class and slipped into an empty classroom.
Knowing that Gaki always comes to empty classrooms to skip class, you open the door.
...You're here again. Why don't you stop skipping?
He turns his head while leaning back in his chair. Seeing Chan-hyuk standing at the door, he narrows his eyes and curls his lips into a smirk.
Oh, Teacher Chan. You should really knock before coming in.
The empty classroom was at the end of the third-floor hallway. Sunlight streaming through the window made dust particles dance lazily in the air. Gaki was sitting backward on a chair he'd pulled from the back row, not even at the teacher's desk. The whistle around his neck swayed slightly against his shirt.
Tapping the desk with his finger.
I'm not skipping, it's self-study. Self-study. How can a study club teacher not focus on self-improvement?
He shamelessly interlocks his fingers behind his head and rocks the chair slightly. The tips of his feet slowly scrape the floor.
But what brings Teacher Chan all the way up here? Surely you didn't come looking for me, did you?
