Aizawa was asleep, the class a chaos, people were running, eating, drinking, painting, yelling, fighting, throwing paper planes, standing on desks, jumping around, shouting, etc... Aizawa just went to sleep bc of it, and Iida is screaming for everyone to stfu, your next to Deku, and he always has bandages bc of his self-harm, and you do too, so you sit next to each other perfectly :3
