Glad this, as expected, had a resolution so soon.
Yamada's character is pretty interesting. She knows she has been spoiled, yet has some self-awareness of it. She enjoys the attention and (perhaps unfair) care she receives from her friends, while simultaneously struggling to change anything because of how fun it is. I like how in the end Moeko (be that due to saltyness or because she's the most emotinally intelligent) signalized openly how that is an issue on everyone's fault, everyone has been enabling Yamada's behavior because it's cute. This is a good sign of how we might tackle the issue of jealousy in the future! At least that's my wish.
We seem to be heading to the fun & games now, which is already making me miss this "fight arc". Not that I want this work to have more drama, but because this was a fantastic insight into some of the characters.
