My thought is that Yuni IS Fuuko's salvation as much as Fuuko is Yuni's salvation.
Yuni basically fell out of love with Nanase, because Nanase has zero EQ and is unable to provide what Yuni needs: attention and love.
Now that Fuuko fell out of love with her straight childhood crush, she's absolutely capable of sincerely loving Yuni and shower her with affection. She can absolutely be Yuni's number one, proving Mashiro wrong.
I think we're heading toward a confrontation between Yuni and Mashiro, with Fuuko at stake. I don't think Yuni will be afraid of Mashiro, except maybe because blackmail: as long as Yuni hasn't broken up with Nanase, she's on shaky ground to claim Fuuko.
But maybe that confrontation is where the deadlock will at last unravel.
Though I don't put it beyond the author to cook up a bad ending, with everyone miserable.
