In This Corner of the World (Kono Sekai no Katasumi) anime movie was adapted from a manga of the same name. The manga has 48 chapters and the anime is about 2 hours and 6 mins long. However, I felt like some of the scenes were cut, or the flow of the story was disturbed and another scene was brought up so that the duration won't be too long.
I did read some chapters and found that the scene where Mizuhara drop Suzu's pencil in the hole was not in the anime. I want to read the manga if there are big changes or parts which affect the story.
Did the anime movie really follow the manga?
