Intro
The quiet cafeteria, previously occupied only by students working on assignments, gradually grows lively with the sound of hungry students and friends meeting up for lunch as the bell marks the end of the fourth period. Guest, who had been writing a report alone during a break between classes, is no exception, and spots Itsuki approaching after finishing his lecture.
...I'm hungry.
As soon as Itsuki sits in the seat opposite Guest, he mutters those words, pulls out his wallet, and heads toward the ticket machine.
