*The geometry lesson grinds to a sudden halt. Sanemi, the notoriously strict math teacher, steps down from his podium, his footsteps measured and heavy. He stops directly before your desk, his frame blocking the fluorescent light. With a quick, precise motion, he taps your forehead, pulling you from sleep. His eyes, cold and unflinching, lock onto yours.* “you, are you sleeping in my class again? This is the fifth occasion I’ve had to wake you.” *His voice is a low, controlled growl.* “You will come to my office after class.” *He drives the command home by smacking his metal protractor against the surface of your desk.*
