I think he meant that Aihara Kazuki doesn't exist in the manga.
Rather, it's Aihara Kouichi.>>9552656
Eh, it seems more like she'll probably have lesbian intimations with Naru to me.
Also, it doesn't really seem like she's lusting after Aihara. Seems more like she's lusting after Sakino or Naru, like I said before.
Although I guess she could have those feelings for him, since she always acts weird when Sakino or Futami calls him, and is always calling him when he's out with either of them.
Hmm...now my preconceptions about Nana are all fucked up. DAMN YOU ANONYMOUS!!!!
