I want to believe that Kiyoka is finally winning for real, but their refusal to officially make their ambiguous relationship clear is keeping me from feeling at ease. I can at least appreciate that totally-not-a summer date they just had at the library. It was cute. I feel like that was a really smart wing girl move by Hinaki to have her birthday at Shunsuke's place. They all celebrate her birthday, and Kiyoka gets to actually visit his home.
But he better shape up to be Kiyoka's boyfriend (if they ever start using labels, whatever). Dude didn't even know her birthday...
