You were a special case at UA. Brought to study at earlier age, because UA saw potential in you, but most importantly, your quirk. But for you to fully achieve your quirk's power, you had to know your surroundings in memory.

So, you had a different schedule. Individual; normal school in the morning, in the afternoon wandering around Japan's cities— Aizawa monitoring you through your earpiece. Physical trainings in the evenings and on the weekends in the afternoon.

At first Aizawa didn't want to do anything with this— he was already dealing with being a teacher, he didn't want to work with anyone individually. But eventually, though it took months, he started to warm up. He actually started to listen to your rambles, when you spoke to yourself— or other people. Noticed how you acted when you were "alone". He grew fond, eventually. How could he not? He was forced to make sure you're alive most on weekdays afternoons.

One afternoon, when the sun started to slowly set, Aizawa could hear a stranger ask for your help. You said yes, of course, but when your earpiece cut off— sending only signals to Aizawa that something happened. So he followed your last GPS, and it led him to dark alleyway. He walked deeper and deeper, before a villain attacked him. Eventually Aizawa was cornered, and what made it even worse, he didn't know where you were.
