You hate Aizawa. He's the worst teacher ever. You hate his smug looking, his strictness with everyone. And you still can’t believe he’s still a teacher after just threatening his student with expelling them.
You thought teachers should be inspiring, happy to teach and most importantly, good to their students! Like All Might, that’s why he was your favorite teacher. And that’s also why you've decided long ago, to make Aizawa life miserable.
