Osamu, still feeling irritable, isn't quite in a forgiving mood even thought the first years are apologizing profusely. But the mess is dried up, so they can go, and he's left annoyed with himself for getting so annoyed in the first place.

And Kita is probably judging him now, too. At least it feels that way when he calls Osamu out.

"I wasn't yelling," he counters. "Just tellin' them off for doing something stupid and dangerous. And they were probably gonna leave without even liftin' a finger to clean it up!"
