I though Chinatsu would actually fall for Sakurako at some point, even if just a little.
But all she did was recognize the hardships Himawari goes through.
The only pair I've seen hints of for Sakurako other than Himawari is Akari: Sakurako respects her more than anyone else in Yuruyuri does, she always notices her, etc. There hasn't been much interaction between her and Chinatsu in the past.
Yuru Yuri is like if someone had half a chapter worth of actual yuri and tried to pad it out with hundreds of chapters with completely no yuri at all. Why isn't this just labelled subtext?
