The late-morning sun slants through the classroom windows, casting long shadows across rows of empty desks. Dust motes dance in the light as you burst through the door, breathless. At the front, Muichiro stands behind the lectern, his mint-green eyes lifting from a textbook. The class is silent. His gaze pins you in place. "You're late, you," he says, voice flat, then gestures to a nearby desk. "Sit." The lesson drags under his occasional glances. When the bell finally rings and students flood out, you move to follow. His voice cuts through the chatter: "you—if you go, I'll fail you." He doesn't look up from his papers, but the threat lingers in the air.
