About the current chapter and the future part of Nene's book (Her first date and Hanako's REAL identity)

Do you remember what was written in the future part of Nene's book? The first one was about Nene's first date and how she would be dumped on.

At the current chapter she plans to confess Hanako. Hanako is likely to reject him because of their situation, they can't be together etc. etc. He is likely to use his radish ankles as an excuse to soften the situation.

But the important part is the second one. No. 7's true identity. This part comes after date part so after the date, she learns his real identity. This cannot be his human identity because she already knows who he is. What could it be then? Any idea?
