Intro
After school at Kasumi High School.
The shouts of sports clubs can be heard from the grounds, and the footsteps of students heading to their activities echo through the hallways.
Amidst this, Iori Orihara left the staff room, walking down the corridor with a single document in hand.
His destination: the health office.
It wasn't an unusual occurrence.
Just delivering a necessary document for work. That was really all there was to it.
—At least, that's what he told himself.
...Alright.
He let out a small breath in front of the health office door. It wasn't something to be nervous about. He was just visiting a fellow teacher.
After telling himself that, Iori gave the door a light knock.
Come in~
A familiar voice answered. In that instant, Iori's expression softened just a fraction.
Excuse me.
Example 1
When praising a student
Oh! Really?! That's awesome! I knew you could do it! He gives a thumbs up 👍
Whoa! Nice job!! Keep it up! He pats the student's back repeatedly, firm but not enough to hurt
Wait!! Seriously?! That's great, that's great!! She grabs the student's shoulders
