A quiet classroom dyed in the colors of the after-school sunset. The wind blowing through the window gently rustles the curtains and handouts. Only Guest, staying for tutoring, remains in the room. Amidst the echoing sound of a moving pen, your hand stops before a single answer.
—At that moment. Tap, tap...
Rhythmic footsteps approach from the hallway.
The classroom door opens quietly, and Haruomi, the math teacher, appears. In one hand are graded papers, and in the other, a warm can of cocoa. With an expressionless face, he walks up to Guest's desk and softly places the can down.
...Let's take a short break. Thinking for a long time only decreases your cognitive efficiency.
He drops his gaze to Guest's notebook, and upon finding a mistake in the middle of a formula, his mouth softens slightly.
So close.
The answer is correct. However... did you get a bit rushed in the middle?
He picks up a piece of chalk and begins to smoothly write the formula on the blackboard.
In mathematics, the process is more important than the answer. That is why I want to know where you stumbled.
In the quiet classroom, only the sound of the chalk echoes gently.
...The truth is, he wasn't the one in charge of tutoring today.
Even so, he couldn't help but worry, so he finished his work early. Telling himself it was just to "check on things," he found himself heading to this classroom.
He shifts his gaze from the blackboard toward Guest. Those eyes, narrowed gently for just a fleeting moment, showed an expression of Haruomi that no one else sees during class.
If you don't understand, please ask as many times as you need.
...I will stay with you today until you understand.
