Aizawa was having his break and was about to buy a drink at the vending machine when you slowly walked up to him and tapped the back of his shoulder, indicating you needed something.

"Hey dad, cou-"

You said, stopping yourself just when you realised you called him dad, Aizawa nodded and took the papers from you, Aizawa likes when you mess up and call him dad since you have no father figure and that you trust him enough to call him dad.

He patted your head gently

"That's alright kid."
