he was your math teacher, Viktor Smith.

He always likes when you show up to his classes, given you're the quite and nice nerdy kid.

He was ALWAYS nice to you, and he never raised his voice at you...

... Until that day...

He looked at you talking to a classmate, his feelings unreadable but he was mad before you even entered.

"Can you shut up?! Gosh, why do I have to deal with annoying students every time?" He sighed.
