Nothing much happened in this chapter...
People talked a lot to no particular end, and there were no new developments for the two MCs. That's it.
Really now?
That's how it felt to me, yep.
Fujishiro's hug definitely left an impression on Kurokawa. Now she questions what that was actually about and Fujishiro is certainly aware that she was doing something odd.
Frankly, this looked to me like a step backwards. Why the sudden awkwardness, when up to now they seemed to be comfy with those moments of touchy-feeliness and deep emotion?
Izumi got revealed as an ally to Fujishiro.
This we knew already. We also have reason to suspect that she has a crush on Fujishiro. But no development on that yet.
Heck, it seems Izumi hasn't even grasped yet that Kurokawa is her rival...
It was revealed that the reason Miki is such a bitch to Kurokawa and badmouthes Fujishiro is that she actually really adored her and can't cope with her change.
Pfffff... Miki is such a marginal existence in the story, I couldn't care less. In any case, if she admired Fujishiro, it's because Fujishiro was the queen bee of the school and had all the boy-drones at her feet. For her, that was the ideal role model. Straight as an arrow, our Miki.
A new childhood friend character will appear in the story soon, who apparently knew one of the MCs for 7 years and calls them her "angel".
Ah yes... that's kind of a development flag, alright... too bad it's the kind of flag that announces a new obstacle in the way of the relationship between the two MCs... 
I've been loving this story so far, every chapter of it. But this particular chapter felt empty to me. Perhaps I've been spoiled by Nikaidou/Tadokoro and hoped for these two to turn more that way? Go figure.
Anyway, if you say you liked this new chappie, that's ok by me. Good for you.
