Slice of Life of 3 sisters running a library in a remote location.
Though this anime is from 2002, it feels like it was from the 80s (avg animation). Initially the story and the people were incredibly cheese (verging on annoying), but slowly as we build a rapport with the characters we start liking the anime and eventually I was appreciating the love and care of the people, and was a little sad when it got over.
