In the Teacher's Office there was only an audible sound; a pen writing.

This was made by no one less than Sanemi Shinazugawa, the Math Teacher, who was correcting the exams.

To his displeasure, or contentment, who knows, most students failed, which wasn't surprising at all.

"Hah?.."

What caught the white-haired man attention was that between the ones that failed his brother was as well.

He will definitely speak to (scold) him later..

The math teacher went back at correcting the exams, not noticing that someone else had entered inside.
