I'm a librarian who loves anime, manga, and reading a wide variety of genres.
I finally finished this. It was my "read while sitting in customer waiting areas" e-book (e-short?), and I spent enough time at a couple car places over the past two days to get through the last half.
It was pretty decent for a freebie, but I felt like I didn't get to know Diana and Beatrice well enough to really care about them. Especially Beatrice. The dance scene in the last half was really good but would have been better if I'd been more invested in the characters.
