While writing the text, the soundtrack of the movie has been looping. There are almost no ups and downs in each song, just a little brisk when happy, and a little more gentle when melancholy. Just like this movie, shallowly, it uses Kamakura's extremely beautiful four seasons to hand in a heart-wrenching diary.
I know who Hirokazu Kore-eda is, and I know about "Nobody Knows", "Miracle", "Walk Around", "Like Father Like Son", but this is indeed my first film to watch as a director. If it weren't for the protagonists, this might still be a movie I know but haven't seen.
