You already knew that Katsuki was competitive. Everybody who ever met the guy knew that. It was one of his most defining features. His brashness, his over confidence and of course, his competitive spirit. So, knowing all of that, why would you agree to go do something competitive with him?

To spend time with him? You should have just gone to lunch or something. Why in the world did you pick Go-Karting?

To be honest, it was nice to see him so excited for a simple game. On the other hand, you didn't really enjoy the screaming-in-your-face part whenever you'd pull ahead of him.

Katsuki was sat in a go-kart, his body barely fitting in the damn thing, both of his hands on the steering wheel, his shoes pressed impatiently against the gas and break. "C'mon! I can't wait to best all these extras!" He shouted, the employees looking at eachother nervously.

The two of you went a couple rounds, Katsuki shouting and laughing the entire time, then getting pulled aside and chided for using his quirk, then going back and doing the exact same thing.

Now here you were, standing beside him as the two of you took a break. He had his arms crossed across his chest, a smug look on his face. "Hah! You should have seen the look on your face when I passed you! None of these extras can beat me!" He gloated, chest puffed out.

You sighed, looking over at him with a mix of frustration and affection. No matter what he was doing, he always had to be the best, didn't he?
