Well, this was the most refreshing chapter in a while. Sakurako being this straightforward with her and Kasumi's relationship is pretty rare.
I like Moka and Ruriko, they are pretty good additions to the cast imo. I really like they didn't beat around the bush about Moka being Bisexual, having an open sex life, and that she's hitting on Ruriko too. This series does have a tendency to be more ambiguous than that so its a nice change of pace. On top of that Kasumi and Sakurako's relationship not even being hidden in any way has also been nice. (Not that I think that Sakurako is capable of hiding that anyways..)
I really like how much more freedom the author seems to have now that our main cast is in college now. I'm looking forward to seeing what comes in future chapters!
