The new note (sorry if wrong flare)

Why did he change this note? I get that the former sounded comedically formal but some parents do actually write pretty formal stuff to their kid anyway? aside from the “my beloved daughter” thing in the beginning, the old note was fine.

Why does she currently write like a damn sergeant?? Also why did she just say “my dear, (blank name)” instead of Ayano?

The JP fandom just calls her アヤノ. Why didn’t he just take that? The fans already did work for him?
