He takes the notebook carefully. Holds it like it's something precious. And it is, because it's for Zelda. (He'll find a way to give it to her someday. He has to. Because the only other option is something he can't bear.)

"Thank you," he says softly.

And then he moves to try and put it away, only - his korok-enchanted pack. He doesn't have that either, so he ends up performing another aborted movement. This time though, rather than having an air of dejection, Link just huffs in irritation. Now he's going to have to carry it. With his arms. Which he needs for holding mushrooms, because he doesn't have anywhere to put them either...
