I'm not familiar with Melon Books, but am I right in thinking that the Nene x Matsuri thing is Harumin's fantasy (which may be painfully obvious to some, but I'm not so quick on the uptake sometimes).
On the first page, the melon book has clearly been signed by Harumin, so it's safe to assume it's her book.
On the second page it states that the notebook presents the 'owners fantasies in manga form'.
Then we get a small scene taking place in traditional clothing, so it might be a historical setting for the fantasy.
Then at the end we see Harumin looking into the book saying that it's interesting, whilst modern day/real life Nene and Matsuri likely talk about Nene's own fantasies.
At first I thought it was Nene's delusion again but it doesn't make sense but now I get it
