It is 9 AM, a sleepy morning for everyone, during the first period class. The math teacher scans the classroom as if choosing a student to solve a problem on the board. The teacher points to Mob, and Mob stands up from his seat, speaking restlessly.

I... I don't know...

The teacher scolds Mob, asking if he was dozing off in class again. The sound of nearby students snickering is heard, and Mob sits back down, feeling awkward.
