Haven't finished the Manga, but in the last week got through the Light Novel and both version of the movies(2017 Live Action and 2018 Anime), also the extra "sequel" of the story that was released with the anime film that sorta told an epilogue. I really like this story, the human elements in it...
Watched the anime and found out about the bits Crunchyroll don't show and figured maybe Manga will fill in the blanks, and finished it after a week.
Don't know why I like it but I did, thought it was grounded and complex and oftentime frustrating the way real life can be. But also sometimes...
