wait what?
It's actually in Tawawa VIII+α, but yeah. It's the omake/extra series that gets added to the compilation books. In that one it has the various main girls all talking to each other about their respective romances (except for Kouhai-chan, who seems oblivious to her own circumstances), and there's a brief spot where Sada-chan shows up to be interviewed by the others. Ai-chan pretty much faints immediately (full white eyes and foaming mouth) when she sees the ghost.
