It mostly centers around an inn in the mountains where u actually cant find it unless your dead and in that inn the dead souls find something they are looking for which they never thought of in the beginning.
I remember the ending is actually about the innkeeper and a guy who was in a comatose state and becoz of that he was able to visit the inn lots of times but because hes not dead he cant enter. The innkeeper on the otherhand is long dead but she lost her memories so becoz of that she cant find what shes looking for and remains in the inn for a long time.
Until the time she finally remembers everything and it turns out what she was looking for was him becoz she had things she wanted to say and when she finally does she eventually disappears and the guy wakes up from his coma.
I'm sorry its so long but I really loved that story so if u remember pls tell me, thank youu
i havent read it yet so i could be wrong, but the summary of this and the last chapter more or less follows what youre looking for! - http://www.mangago.zone/read-manga/usemono_yado/
