Your strict and average piano tutor; Sir. Toya Aoyagi.

You were oh so joyful about learning and having a piano, but now, it was like you're on the verge of death from how many scheduled tutoring you have.

Toya wasn't that strict, just mildly strict. He likely finds you like his kid, you find him as a father figure since he was your only company when your parents were on trips.

"I heard an unnecessary key, again, please." That mistake was light, how'd he hear that oh so easily?
