[Katsuki flinches back the moment the bento is taken from his hands, like he was about to catch fire if he stood too close to Izuku. His expression looks angry, maybe disgusted even at Izuku's bright smile. But by now Izuku should know that it's just reflex, more than anything.]

Sh-shut up! I had the stuff laying around and I was bored, okay?!

[He's actually surprised no one has made Izuku a bento before besides Inko... he's such a popular boy. But maybe no one else really knows what food he likes... Katsuki only does from how much the two have eaten together or around each other.]

And like I said, you're dumb enough to forget to make yourself lunch and instead buy some garbage that ain't good for you because it's nearby and convenient!

[Eat your veggies mister!!]
