Oh wow, I've read this up to chapter 13 or something and forgot about it for years. It's actually this far already, huh? And of course on permanent hiatus, this is Namori after all.
Hm, now that I read it all in one go, I believe Nadeshiko's secret gf is Ai. Her reactions are the most suspicious for someone who is portrayed the least direct. I could probably write an entire analyses on this, but what's the point if it never continues? lol
I'd say this needs more SakuHima, but the main series had tons of that.
