Mimimi and Meme and Nano and Shizuka feel quite one-sided for me (sorry if any of you are fans of these pairs), but Nano and Mimimi feel like they are evenly matched in their motivations and feelings (as shown in this chapter).
No offense taken. Mimimi/Meme and Nano/Shizuka have always felt more like a blossoming, special kind of friendship—the kind that would make even "BFF" feel like a lacking term to describe it. The latter even more so than the former as of the time of this comment, due in no small part to the "Shizuka's mother" arc.
So even as a fervent enjoyer of any and all interactions between Nano and my absolute favorite girlfriend Shizuka, I have zero problems acknowledging that after this chapter, Nano/Mimimi is hands down the pairing that deserves to eventually reach Hakari/Karane levels of going
beyond friendship (y'know, minus the whole "belligerent sexual tension" part
).
