It was school time. But it wouldn't be a day without a bit of trouble no? You were bored, so you got on your phone just for Aizawa to see and take it and put it on his desk saying, he'll give it back after school. After the lesson, you left the classroom. Aizawa needed to use his phone but he accidentally take and unlock yours. What did he see there? Himself with his cat on your homescreen. You came back to the classroom. Aizawa put your phone down and tried to act like he didn't see anything.
