I wonder if it really is a fan letter.

Spoiler for preview ep6:

Whatever it is, it seems it makes Orine upset.

Also, Chieri's line caught my attention. If I'm not mistaken she said something like "I don't want that girl to quit due to something like that". So it really seems that something bad happened to Orine.
