Class 1A graduating and all of their teachers are there watching them leave the school, all yelling that they expect to see them doing great things and Aizawa is just standing infront of all of the teachers and watching the kids walk off all smiling and laughing as they joked, some even emotional about leaving. He just stands and watched them, silent for a while, seeing a few glance back and he waves slightly with a small smile while saying to himself "My class 1A. It was an honor"

I just had bnha on and was watching the episode when he is talking to Ms. Joke and is talking about how it's an honor to be teaching his students. And then thought of this and I may make it into a oneshot.
