it was the very first day at UA high. Everyone was already in their assigned seats, even Mr. aizawa was already there. The bell rung and Bakugou noticed there was a seat empty. He spoke up:

he looked annoyed, but a little amused by the fact that this person was late.

aizawa sighed and began teaching. He was tired and was visibly waiting for class to be over.
