Ep 12
Well, overall a pretty good ending to a good series that was a pleasant surprise on the whole.
I kinda like the quiet, roundabout way they showed hints of Nozaki being aware of Chiyo - but it is kinda frustrating for me being the type of viewer I am.
Still, as others said, at least she "got it out of her system". ^^
I would not mind giving s2 a try, though, and wouldn't be surprised if we got one eventually.
