I was thinking about this when I was reading the story of the relationship between Dia and Fio in Corti, and it said that Fio's parents were sad when Stella passed away, but when Fio appeared dressed as Stella, their tears stopped.
Fio continues to dress cutely for both herself and her parents, but it gives off a dark vibe, as if Fiori isn't needed, and it's a bit sad.
I can't see the Magnificent Event anymore, but I'm really glad that Fio has a place in Corti, where they accept her both as Fio and as Fiori. Fio
