In my eyes, while I don't see it being build up as much as "I see you Aziawa-san!" yet, it is pretty similarly a manga of, wow just a cute lil Yuri premise, where said premise turns into a big mystery. So yeah, first Volume has to do a lot of establishing work, but hey it pretty. While i don't see where it's going, maybe that makes you not immediately cancel it. Don't remember it too much right now for a longer review, tho I do like the characters and their motivation or rather the lack thereof.
