[Honestly if he'd said that, then it'd be Shouto combusting. Katsuki choosing him--maybe he's already realized a little, after all he'd trusted Shouto enough to come to him to moonlace, and to stay with him during the last three days in that vulnerable shape, but it's different, feeling something like that and actually hearing it.

Then again, the way Katsuki turns red and gets techy about it is pretty nice, too. Shouto at least feels confident enough to keep going as he shovels the last of his rice into his mouth, swallows, and tilts his head questioningly at Katsuki.]

Was that 'I'll kick your ass' supposed to be 'thanks,' or 'I'm glad'? Sometimes I have trouble figuring out which one is which.
