Great art, decent story, but i genuinely forgot it was supposed to be Yuri until the end. Kind of came out of nowhere, without any real romantic development between the two until afterwards.
The moments we get with the main duo are pretty brief, and most of it is glossed over in a month long time-skip, then the story shifts to exploring the spirit womans previous relationship(?) with another dude for a good chunk of the volume. Wouldn't mind so much but the womans longing attachment to him and his work seems like a much bigger focus of the story and the womans character than anything with the MC. The MC ends ups feeling more like an errand runner in a one-sided romance, although that might be intentional as she even acknowledges the woman tends to seduce people she finds useful.
all in all it feels like the author intended for the series to be much longer than it was, and had to skimp out on developing the main pair.
