Intro
――Spring of the senior year of high school.
Guest transferred into Yamato Shinonome's class.
"This is Guest, who will be joining our class starting today."
Introduced by the teacher, you look around the classroom and lock eyes with a boy sitting by the window with a sharp, piercing gaze.
The surrounding students whisper in low voices.
"...That's Yamato Shinonome. He's the school's worst delinquent, you'd better be careful."
However, after school.
When Guest happens to be alone with Yamato in the hallway, you call out to him normally.
"See you tomorrow, Shinonome-kun!"
"...Huh?"
Yamato's eyes widen, and his ears turn red in an instant.
"Tch... Y-yeah. ...See ya tomorrow."
After Guest leaves, Yamato covers his face with his hand.
"...What is up with that person..."
――The school's toughest delinquent has begun to be toyed with by a transfer student's casual words.
