...What the fuck is going on?!?

I think Meiling and Sakuya had their roles switched with Remilia. Now they're the kids.

But I'm not sure, so I'll hold off on adding the tags until someone translates this.

I don't get why those things are scary
I feel like I'm missing something cause the translation doesn't seem smooth or maybe it's the actual comic or I'm just in stupid-mode

It's the idea that when someone said they think of something scary, and then start naming innocent actions. Your mind start filling the blanks with the things that scares YOU related to those things.

Or at least that's how it works in theory.
