A few chapters ago Yuni said she wants Nanase AND Fuuko.
In the previous chapter, Fuuko said she doesn't want to separate them as a couple, but she wants Yuni.
In this chapter, Nanase did not break up with Yuni. And she wants her club AND her GF.
Conclusion?
Simply, none of them can function EVER as separate couples (Yuni-Fuuko, Yuki-Nanase, or Yuni-Nanase).
Their personal interests (and secret desires) can't be fulfilled through one-on-one relationship.
For one-on-one relationship every character here must cut of "their own right hand", sacrificing something what fulfills them from the other side, equally important to them.
If they make a choice, not getting all they want, they won't be complete anymore:
Yuni has some dark desires which Fuuko fulfills.
But without Nanase in the game, there's no thrill. She wants to be watched, getting "the special attention".
And (in previous chapters) Fuuko called her "a pervert", teasing her, because she knows what Yuni truly wants. And she is getting off too, as Yuni's "side chick", as she says to Nanase.
But, the only difference is that Fuuko is OWNING all what she feels and wants from the beginning, and Yuni is (partly) in denial.
It was the bullseye, telling Yuni :
"Was it more thrilling to be terrified she will find out?"
Yuni bites her (with death wishes), proving her denial, and Fuuko feels the thrill, knowing she was right, reading Yuni perfecly again.
Fuuko is the only character who wants to bring on all those dark desires into the light.
Revealing all was the right thing, making Yuni and Nanase look up into reality and into the depths of themselves, facing their own darkness, imperfections and wrongdoings. She wants them to accept their true desires and needs.
All of them know what they want (secretly or not, mostly denying or trying to find solution), but only Fuuko acts on it fearless. And that's her quality as the person.
It does not matter how f-up she knows she is, she is owning it and does not want harm to others who are involved.
She has my full respect as the person (fictional or not)
Now, Nanase must make her decision, after processing everything.
At this point, we don't know what her final decision will be.
Her only option to get her club AND the GF, is to accept Yuni-Fuuko side relationship, or start a new relationship with Yuki (I think it's less possible, because she still feels very strong for Yuni, after seeing her own mistakes as a GF, and Yuni's "ghost" is following her while she walks with Yuki, so she is not over her, seriously considering quitting the club and choosing Yuni after all)
There is a strong bond formed between those three girls, it's not quite easy to break it all up, just like that. Too many emotions and persons involved, intertwined mutually.
And yes, I think there is the true love between them, however f-up every character is in its own way. It's the way of self-discovery, full of thorns.
I wish for happy Nanase-Yuni-Fuuko ending, I'm not cruel to wish for disaster to any of those girls who are making mistakes of youth, discovering about themselves and the world. It's hard to fix all the old "norms", just to start breathing.
Thanks to the author for amazing work. Everything is spot on. The perfect pace of developing the story and the characters.
