I watched the film a while back and I listen to the soundtrack frequently. It was the most moving film I have seen, I think, possibly because I watched it at just the right time to feel a certain way. Right now I am at a similar point, so seeing this feels like a stroke of luck.
Interested to see what, if anything, is different between the film and manga.
Edit: I just noticed a detail in the third volume's cover that feels like foreshadowing...
