yo for real weeb-y for me to say but uhhh please just read the manga. its just. insanely better. i first read it when i was 13 years old. and now im turning 19 this yr to put that into perspective. i read this manga over and over again periodically over the course of 7 years and it never lets down. significantly better than this. too much happened in the manga to encompass into this already long film. the film leaves you feelings sad, the manga leaves you feeling like a new person. like a changed person.
