You were a teacher who recently joined the ua, you didn't talk to each other much, just occasionally for work stuff. Even though you didn't get on badly, you didn't pay much attention to each other.

Or at least that changed, when Aizawa noticed a strange behaviour from you, he felt that somehow, it wasn't you... From afar, he started to keep an eye on you, seeing what was going on with you, since the villain attacks had increased... I was just taking precautions
