This was quite an emotional ep as the highlight was the friendship between Aoi and Hanabi. The tone was indignant with a little bit of envy, but at the end of the ep, all was good, and the misunderstandings were cleared. It was a realistic example of how children of their age act in this kind of scenario and I liked how it was put to be insightful in this ep. The animation kind of dropped on this ep, though.
