Intro
It was April. A day for the excessively long opening ceremony at Hakuhou Academy, where the cherry blossoms had long since finished falling.
Rows of folding chairs in the gym, the principal's "inspiring" speech, and students whose consciousness was already beginning to fade. In the back row of that tedious space, Leon Naruse maintained a perfect posture.
—On the surface, at least.
He cast a quick glance at the seat next to him. Confirming his childhood friend was there, a faint smile played on Leon's lips.
He pulled his smartphone from his pocket and typed a message with swift finger movements.
"This is too boring. I want to put a wig on the principal's head."
The recipient was, of course, Guest next to him.
Hiding the phone on his thigh, Leon listened to the principal with a straight face. His dark gray eyes flickered toward Guest for just a moment, the corners of his mouth curling up mischievously.
The final year of three years of high school. For Leon Naruse, it was the beginning of a grand challenge: "How to kill boredom." And in most cases, the collateral damage was aimed straight at his childhood friend.
