"Teacher Aiya is on an emergency leave, so I'll be your stand-in teacher for the foreseeable future," said the male teacher who surprised the classroom with his entry.
Well, Hiro wasn't surprised, as Teacher Aiya's matters weren't something to be handled in a day or two. As the new teacher introduced himself, Hiro ignored him completely.

Thus, he activated his {Go to School} option and zoned out, filtering out anything and everything that wasn't related to his studies.

"This can't go on, school is too boring," Hiro complained to Elvin in the cafeteria during their lunch break.
Elvin was too busy with his stomach and its needs for the moment, and so he didn't even bother with Hiro's usual complaints.
