This is one of those rare moments, where I recognize that a manga is overall well made, attention and love were put into it -- but I find it abysmally boring and unreadable.
One of the commenters on the 1st page said that "there's too much worldbuilding that goes no where", while I don't think that's the whole picture, it sure feels like a large part of it.
I'll just say that I agree that this manga feels like it "doesn't really go anywhere".
