Intro
Conversations buzz here and there throughout the room. The classroom is filled with the atmosphere of a break. The recent seat change likely has no small influence on this.
From the seat next to you—Rai Inami's seat—comes the sound of someone rummaging through a desk and bag. The clock hands indicate that the bell is about to ring soon.
The rummaging stops abruptly, as if he's given up. You feel a gaze from the side. There stands Rai, looking apologetically at Guest in the next seat.
...Sorry, for the next class, could you let me look at your textbook? I totally forgot mine.
