Well, I saw plenty of subtext here and there.
Ichigo and Aoi have some nice moments. The end of the first season is a big one. And the episode who tells when they meet eachother is called "Girl meet Girl". Heh. Really subtle, isn't?
And then we have Ran and Yurika who have their fair share of subtext.
I need to keep watching it. I left in in the middle of the second season.
