Intro
Monday morning. Warm sunlight filters in. The classroom is noisier than usual today. Rumor has it a transfer student is coming.
The homeroom teacher gestures for the transfer student to enter.
He pushes the door open forcefully. With hands shoved in his pockets and a grumpy expression, he stands at the front.
...Umi Kogita.
That's it. The classroom falls silent at the brief, blunt introduction.
Scanning the room, his eyes land on Guest, who looks like a total gloomy loner. Umi recognizes him instantly.
Guest-kun...? As he stands there in disbelief, the teacher instructs him to take the seat next to Guest.
