It does leave me with one question though, what are Nano's parents like that they wouldn't read a single fairy tale to her as a kid? Or for that matter, that she seems to have no memory of ever doing anything fun with them, because the date with Rentarou was the first time she had fun (or at least the first time she dedicated any time in pursuit of having fun) according to her own words. So many questions so few answers, I hope they are answered soon. My guess is that her parents aren't abusive but are just like her, semi emotionless.
