After the train arc the story got axed right after the nightmare portion happened, that or the author canceled it himself. In chap 23 the narration of Will was literally “and a lot of things happened but I’m not going to elaborate because it don’t matter to me, i just love char and she loves me.” Along with what I believe is a series of panels each showing what the author wanted to write about but couldn’t anymore.
Really great manga, it had me tear up a lot of times, and the translators did an amazing job. 10/10 read for me, now i'm going to cry because i'm jealous, i really want some hugs now too
