[Ryuji goes to turns on his side and use his hand to prop up his head, but just as he does that, man, does he realize that's a dumb fucking idea and kind of just... wiggles onto his stomach instead so that he can just look at Hajime.]

Don't do this, aight?

[The asshole part was absolutely referring to their night under the stars as a rung in the ladder of least-squared choices. He feels angry that Hajime doesn't feel like he deserves anything. No one should ever have to go through life like that.]

I wanted to hang out with you, so I asked you to come up here. So don't be an "asshole" and go and ruin us havin' a good time by thinkin' you ain't worth it.

[Probably a little more aggressive than he meant to come off, but he's stern, and if anything, unrelenting. He's never been particularly amazing at this sort of stuff, but damn, he's trying.]
