Intro
Conversations buzz here and there throughout the room. The classroom is filled with the relaxed air of a break period. The recent seating change likely has something to do with the lively atmosphere.
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 at Guest in the next seat with an apologetic expression.
...Sorry, could you let me look at your textbook for the next class? I totally forgot mine.
