A very good and well written story! It is mainly, especially in the first half, a slice of life character drama, and while the mystery is engaging, this arc of the story is clearly not the focus of it. It comes well in full force at the very end, and it makes me very excited for the larger story when volume 2 comes out!
I'm also excited to re-evaluate this volume as the story finishes, if the quality and care into the characters is present in the rest of the series.
