It's quite obvious, when I think back on it, why I felt so off-put about the ending of Pita-Ten when I first read it.  The ending is about moving on, about letting go, about new hope, and embracing the brightness that still remains in life even after the shadows.  But I couldn't accept that yet, because I myself wasn't ready to move on.  I still wanted to cling to the past, and I wanted to remain in that state...I didn't yet have the courage to look forward.
