[ It's not that Chizuru doesn't understand why people don't like to show all emotions in front of others - especially the negative ones. She was surrounded by those types back home, and even she doesn't like crying in front of others since she feels like it might be a burden.

But even so.. ]

I understand. But I doubt anyone would mind seeing you like that either. Feeling sad is only natural when something like this happens. If someone I knew from back home was here and disappeared, I'd probably be so upset that I wouldn't know what to do.
