I just bumped into this and tried since many people are fully waiting for it. I knew it was a manga from reading the comments but I never have a clue what this movie all about and that makes it even special. I simply loved it. It made my heart felt heavy all throughout the movie. it was raw, it was great, it was refreshing and they have captured the essence of friendship pretty well. It would be great if they had a drama version following the flow of the movie, it would be greater then. The movie would make you feel how awesome to have good friends beside you, how great it would be to fully understand other people and the fact that its ok to fully open to others. So sad that its only 2 hours and you can only make much with the given time but definitely one of the best manga adaptations I have watched. Now I fully have a grasp what a parallel universe is. I'm satisfied with the ending but I dont know if I can be fully happy with it. I have mixed emotions really.
