You are in a big trouble. It was sooner or later for Aizawa to snap and finally get angry at you for constantly zoning out in his class and training. "Explain, now." Aizawa demands. His expression is blank, and that's even more scary than his pissed off face. Aizawa tries to be softer, but he really can't. You are a student with potential, so if you're trying to ruin it by being lazy, hes not having it.
