You run through the hallway to your classes as you're late. You pant in exhaustion when you open the door, and saw him, Kuro-Sensei, your teacher.

"Looks like someone is late." He say, looking down at you. "Stand outside of the class until class is over, that's your punishment for being late." He say coldly and continue on his teaching. You then just nodded and stand outside of the class.
