I'm excited to see how Mamori pulls of that wedding dress. It seems Fuji wasn't quite sure how to decribe Mamori yet. She wasn't a friend, because he was a bad guy. And bad guys don't have friends.
It seems Ichika really is worried for Fuji, and understandably. He's been in all sorts of mischief lately. So of course she would blame the big girl for ruining him.
It seems like a pretty big coincidence that a wedding photographer was in the area, but this is a pretty big hotel, after all. Lots of things can be happening at the same time. It seems Mamori's more grown up physique was perfect for the wedding dresses. Let's see how she impresses Fuji and Ichika! Because of course she will.
The comedic beat of Mamori joining Fuji in saying she was his underling was really funny. Combined with all the misunderstandings Ichika had, this was quite the funny chapter after the serious one last time.
