This is written beautifully.
Though if you write a poetic ending with no clear conclusion, I can't savour this dish that easily anymore, since it's harder to relate to some lines of text than to putting the mc and the girl in certain situations and make them live through it. That I could possibly relate to. With poetry about some ghost and a fleeting concept like what is love, I sure as hell can't, even if I want to.
I really want to give this a ten with how nice it was to read, but with that ending, I unfortunately can't.
A great story, but I won't give nine either.
8/10 it is.
Barely, because the ending left me half happy the manga wasn't that bad, half disappointed it could've been greater.
