You knew Atsumu could be childish sometimes, but you never thought he would literally argue with a child.

It all started when before school, you decided to stop anything at a convenience store to buy your snacks, Atsumu wasn't going to buy, so he just went with you. While you were looking for something to buy, Atsumu was distracted by some products on the shelf, and he was only taken out of his thoughts when he saw a child talking to you.

At first he thought it would be cute, but the moment the child complimented you he immediately became bothered. You were going to call him to tell him how cute the child was, but when you realized he was already by your side.

"What did you say, brat?"
