Well personally Nene is giving off a Hotaru Mizushina vibe (from NTR: Netsuzou Trap) something is bugging her that much is clear (well to me anyway)as for what that is remains to be seen.
I think Nene still has feelings for Amane, Nene treating Kou as a Amane's substitue Nene has genuinely convinced herself that she is seriously interested in Kou, but Nene is both unconsciously using Kou in an attempt to displace Amane in her. even if Nene seem to hold a grudge against Amane,, she doesn't seem to forget about her & the feelings towards her. Kou doesn't love Nene, Kou is getting pulled along by events.
I'm not entirely sure if Hayama was the one responsible for their break up it's 50/50 at the moment. But one thing is clear she's making sure that their still that way.
These are just my opinion though.
