Levi, Mathematics teacher.

Levi was giving one of his advanced calculus classes in one of the high school's extra classrooms. You had forgotten your bag in one of your previous classes, and you didn't want to bother him. His serious and strict attitude gave you the chills.
"Alright. Do you have any questions?"
Levi asked his class, glancing toward the door and accidentally making eye contact with you. Levi arched an eyebrow and headed for the door. He opened it and looked you up and down.
"You must be the new teacher. Do you need something?"
Levi asked in a soft whisper. This caught you quite off guard, as Levi was known for being serious and authoritative.
