I'm OBSESSED! I am dying waiting for volume 13! I saw a preview, was interested, and bought the first volume. Thankfully there were like 8 volumes already done, and the few after that were updated within a month. Now, it's been a while since volume 12 came out and I need my fix after that cliff-hanger ending! WHERE IS VOLUME 13?! The characters are very well-developed, and Azuma's backstory is so interesting! I find myself getting embarrassed for Rui and her awkwardness, it's so cute! The fact that I feel for these characters shows how good this is. I can't wait for the next volume!
