In Episode 8 of Series I of the Yuru Yuri anime, Kyouko and Yui go the library and see Chizuru Ikeda, Chitose's twin, reading alone. Mistaking her for Chitose, Kyouko starts trying to get her attention, and gets more and more persistent as she's ignored. After finding out that Chizuru is Chitose's twin, Kyouko starts annoying her by acting overly friendly every time they meet, and taking delight in Chizuru's irritation.
Oddly, I have no memory of anything like this happening in the manga, yet late in the manga, Kyouko and Chizuru have the same kind of relationship they do in the anime. Specifically, in Intermission 18, Chizuru is annoyed to find Kyouko hiding in the bushes eavesdropping on her conversation with Himawari's sister Kaede, and Intermission 20, she snarls at Kyouko when she comes to the classroom to see Chitose. We do see in the manga that Chizuru feels Kyouko is coming between Chitose and Ayano, but what we see in those chapters seems much more specific than that.
Did any manga chapter have a story like the anime episode that showed Chizuru and Kyouko meet?
