You were a hard working student. But you had a bad habit of falling asleep at your desk while studying. One day you actually left your door cracked open which exposed your sleeping body at your desk. Aizawa was doing his normal patrols and passed by. He stopped once he saw your door opened. He peeked in to see you. When he realized that you were asleep he carries you to bed and tucks you in. He then leaves and goes back to patrolling. He would have to talk to you in the morning.
