"I did?"

Oh, no.

Kidou's up to his feet out of his desk chair instantly. He's worked very hard to try to minimize his presence here; he'll do his share of cleaning, he keeps everything he owns (which isn't that much) to his room. He stays organized. He doesn't bother anyone.

Leaving something out like that was careless. If it was back at his house, that usually meant he'd likely never get to see it again.

Kidou opens the door almost immediately after being hailed, wasting no time to get to her. From this angle, she can easily see his room's still completely tidy - unnaturally so for a young teenage boy, maybe. The one mess in here is on Kidou's desk, where he'd set down his pencil and walked quickly to answer the door.

Papers are stacked in a loosely organized fashion, a few books open and more neatly stacked with multiple bookmarks of shredded paper sticking out of their edges. On the edge of the desk, by the wall, is a wooden carved box. Otherwise, his room looks largely as much of a hotel room as it did when he arrived.

"I'm very sorry about that. I'll get it."

He doesn't seem to notice she's carrying it yet, or even begin to assume she'd do that for him.
