Eh, I want Nene and Amane back together, Tarumizu happily still single until she both matures a bit and meets the right person, and warm, stale beer poured on Hayama.
I also think Nene is honestly in love with Kou, but Since Kou is pretty aware she’ll probably sense Amane’s anguish and gee so guilty and conflicted since she’s also catching feelings despite knowing what’s going on.
Kou isn’t to blame at all, but we know she’ll see it as that.
I will go on the NenexKou ship until the reason why Amane and Nene break up is reveal and if Nene is honest with Amane and Nene. If it prove that Nene still have feelings for Amane, which i really doubt at this point, i will go on NenexAmane.
