Koe no Katachi will take you on an emotional ride and has a very beautiful story. If you don't mind dark and twisted stories you can also check out J no Subete and Complex (by Manda Ringo).
Shimamami Tasogare is a little similar. Good one
So this manga is a true masterpiece.
Could someone recommend me similar manga ? Because I have never found a manga with this kind of story as deep and as beautiful as this one (maybe except for Koimonogatari).
