Ok what the fuck is this? Why did it get rushed in the end? There's so many characters that have been set up just to be left out of the story in the end. From the other comments I figured it got axed so the ending is rushed. A shame.
Never thought I would love a manga about a library. Then the manga lied this isn't about libraries(it is), it is about the characters and their outlook in life and how they deal with their problems. People change but they don't change instantly, it takes time to stop and reflect on your own...
