[Wataru is a big dumb idiot and Eichi loves him SO MUCH. He just wishes he could have gotten this earlier so that he could return it with his own thoughts before Wataru had vanished.

It's going to take a bit before Wataru will get this exchange diary back. So Eichi can read it. So Eichi can just hold it in his hands for a time, and so Eichi can manage to get his own thoughts down.]
