- Yazawa also doesn't like her girls to get the girl. I still contend that the main romance here is between the two Nanas, but Yazawa keeps putting guys in between those two. It irks me how she first puts so many romantic overtones between them, only to drop the issue like a hot potato later.
- Jossed - Nana O is seen alive during vol 20 and 21.
Naturally, Hachi raises Satsuki along with Ren. This is why Satsuki refers to a "big brother", and also explains why Yasu is so close to her (at one point Hachi says he thinks of her as his own; Satsuki is his surrogate younger brother's child). Satsuki has long black hair like Takumi, but also like Nana and Ren. Meanwhile, Hachi and Takumi's marriage grows worse than usual, and Takumi takes off to Britain with Ren possibly hoping that this will tempt Hachi to move with him, as he speaks regretfully about the situation to Naoki. Hachi refuses to go with them because she wishes to wait for Nana with Satsuki (who probably has no idea Hachi is her adopted and not real mother) in Japan/room 707. Ren spends much of his time with his father and Reira, and so isn't as close to Hachi and wanders away when he's in Japan; Reira notes that she feels like she "should" dislike him (since he's Takumi's child with someone else), but instead they're quite close.
At some point in this separation Hachi decides to divorce Takumi, as evidenced by Junko asking about it, but when the photos of Nana turn up she changes her mind because Takumi (who seems to be trying to reconcile with her) offers to help search for Nana in Britain. This can even also explain why Hachi and Nobu have become so close again; she was on the verge of leaving Takumi for him (...again), but has backed out for the time being because she wants to find Nana more than anything else.
