That cough is definitely a little worrisome to her. Maybe it's mostly since she can't tell if he's just having a hard time talking or if the cough is the sign of something more serious.. or maybe it's just because she's fussing over the other right now. It's not every day that you find a friend like this out on the beach.

By the time she's next to him, she sinks to her knees into the sand, apparently not even worrying about dirtying her clothes with the sand and the goo.

"Um.. I think I've vaguely heard of it.." Chizuru replies - though perhaps sounding a little absent-minded on that. It's hard to focus and try to remember things when you're busy worrying about a friend, and her hand reaches out to try and brush some of the goo out of Nara'a's hair, careful to avoid his ears. ".. Are you saying that's what happened to you? You-- You went home? Or you think you did..?"

And then he somehow ended up back here, covered in this stuff?
