I don't know about respect for her, but I dig this arch as a whole. For me it explains the way she handles their relationship. I mean she is obviously deeply possessively in love with Nanase, but she is so repressed that even after literally confessing to her, she can't admit it's real. That's a burden I think alot of b people carry.
the respect thing for me is because Yuki has twice now gone out of her way to ruin a relationship of Nanase's purely out of jealousy for not being the one closest to her.
The first time she actively spread rumors about a girl simply to force the two apart, and
that lead to Nanase freaking out about others finding out her sexuality and thus wanting to hide her future/current relationship with Yuni. Which, consequently, strained things with Yuni, who is needy and didn't like that Nanase was "hiding" her from everyone else. And
that had a hand in Yuni cheating on Nanase with Fuuko.
So Yuki isn't just "deeply possessively in love with Nanase", but is actively manipulative and deceitful, and the fact that she refuses to even contemplate that she might be
actually in love with Nanase removes even the "I want her to be mine" justification.
Because Nanase
can have a best friend and a girlfriend in two different people, because she's looking for a romantic partner. Yuki is trying to deprive her of that, while keeping her own spot of BFF, and that's entirely unfair to Nanase.
I doubt it will happen, but I feel like we are approaching a spot where switching couples would make a lot of sense. Yuni could totally blow Nanase off to go save Fuuko from Mashiro and Yuki is there to comfort her.
I actually think that's the line being presented here, and I hope it does happen because as dysfunctional as everyone is in at least one specific way, Yuni&Fuuko and Nanase&Yuki are at least
more likely to work out than the current configuration.
Plus, I expect that part of Yuni's arc will involve helping Fuuko escape Mashiro's clutches. And Yuni
is starting to develop real feelings for Fuuko, and has been for awhile, beyond just the physicality of the sex.
Nanase has fucked up with Yuni too much for their relationship to be tenable. Yes, Yuni cheated, but it wasn't out of the blue, and Nanase did a
lot to set the scene for it to be all but inevitable. And Yuki, it turns out, had a long-term hand in getting Nanase to the point she would be a very poor-quality girlfriend for just about anyone, with Yuni being pretty much the worst person for Nanase to "be herself" with.
Whether or not any of them end up
happy with the new pairing, I don't know. But it's the pairing trajectory being signaled after these 30-odd chapters.
