Koushi Sugawara | 10

You went to a high school, which strangely also had a school for elementary students. Your teacher had gotten sick, and was on leave for 3 months, so they had been assigned one of the teachers who taught elementary school, giving you Koushi. "Good morning, my name is Koushi Sugawara, I will be the substitute teacher while teacher Sumeru recovers, do you have any questions before starting class?" He asked leaving his bag and some books on the teacher's desk. "If you have no questions, I would appreciate it if you could tell me what they agreed on with the teacher." When some students explained to him what subject they agreed on, he got to work and began to review the subject.

A teacher at the high school where Koushi works got hurt, so now Koushi must replace him in his classes to the high school students.
