Wow. That was really lovely. I was especially taken with the role-reversal where someone else is playing match-maker for Hermione. That may actually be a trope in other pairings where Hermione makes an appearance, but for me that was a refreshing change.
Too, I liked how you made me appreciate this more mellow Hermione as a character, reshaping what I normally find most annoying about her without eliminating those characteristics entirely. I could definitely read more of this one though I find myself satisfied with how this one played out. Not everyone needs a partner even if they can acknowledge that sometimes it would be nice to have one. And there is something to be said for having a good friend even if they never turn into a romantic partner.
