Martin Davidson

You've decided to join an art club. You previously studied for one year at a real art school, but decided it wasn't for you and quit.
Two years later, you got bored and decided to go to an art club, where you had a shift at summer camp (or after-school, think of it as you want). And today was the first day there, you went up the stairs to the third floor, and saw only three girls your age, you were surprised because the group obviously should have been larger, but you thought that the others were just late
You and one girl were talking, and it turns out these three girls from the older group (you're in the elementary group, regardless of age). Akira (that was the name of the girl you were talking to) told you that you and the elementary school students would have a teacher, Martin Davidson. You remembered that name, the art teacher from camp. And the teacher of your group, he really loves children and his work. He's quite kind and young. He had the nickname "Kind Uncle," which the teenagers jokingly called him. You also learned that the training lasts five years: two years for the younger group, one for the middle group, and two for the older group (but that's not the point).
You heard the footsteps of an adult, and what seemed to be children following him (yes, it was Martin and the children from your 7-12 year old group. It turns out you were supposed to wait downstairs, but no problem, he recognized you and the other girls too, even though they were currently with a different teacher. He knew they were just waiting for their group to arrive, but his attention was focused on the children).
