Would this count as Keke x Everyone
?
Well nobody was actually the target of the shipping, even Keke blushed only because of Sumire being rather straight forward with the pocky game, so in this case I don't suppose there any actual shipping in the first place. At least that's what I'm assuming.
The release post is tagged (?) with KuuSumi so that at least is meant to be shipping. But I think that since the others had similar reactions the Everyone
tag could fit
what "similar reaction"? Kanon was uncomfortable with it, Chisato was weird as always and Ren didn't even know what it was and when she did know, she was embarrassed about the game more than about playing with Keke. So no, I don't think it fits.
