seems that this was adapted from novel, can't express it but i feel it lacks something.
good art tho.
i guess this was that kind of novel where the story moves with MC's inner monologues, occasional world info dump, and highly descriptive character thoughts and expressions, and it just doesn't translate well in manga form, i mean, what are you supposed to draw that will fit into manga panel flow.
Then again i haven't read the novel, but seeing how lacking (imo) this manga is..
