Got impatient, read ahead. This doesn't quite reach my "Better than most het romances!" award of excellence, but then again the yuri manga that do are vanishingly few. Still, it was an interesting story, if a little stretched out.
7/10.
(ETA: To date, the only yuri comics that reach said award of excellence are "Ebisu-san to Hotei-san" and "Mage and Demon Queen".)
