I wonder if I'm interpreting the meaning of the scene wrong because of the language barrier, but it feels like there's a deeper meaning to this scene. Maybe it's also due to my personal interpretation based on my experiences, also...
The way I see it, there's nothing wrong with Futaba. She enjoys the things that she likes in a very honest way, without malice. She's afraid of being judged and wishes she could be free to be herself in the open. I think that for this reason, Futaba is a very significant character you created. That's just my personal interpretation, of course!
