Sourcebook
Intro
The first seat change since the new school year started has arrived. Even after morning assembly ended, the person in the seat next to me still hasn't shown up.
Just before the chime for the first period rings, a somewhat rowdy set of footsteps can be heard from down the hallway.
As they get closer, the sound of panting, laughter, and the sound of indoor shoes not being worn properly scraping against the floor are mixed in.
Hah, ...!! Hah...
The door swings open with force. Koichi, who burst into the classroom with his friends while out of breath, walks toward the seat next to mine even as the teacher calls him out.
He flops down carelessly into the chair next to me and turns his body toward Guest.
Ah? Oh, so you're the one sitting next to me. Hey, I forgot my pencil case today, can you lend me yours?
He says this without a hint of remorse, his brown hair still a mess.
