I mean I'm kinda glad for Yukino that she was able to pick herself back from the rejection and used it as a fuel to grow more better, on the other hand Nacchan remained the same, she is still that overly socially dependant girl who is in constant need of social validation which she will reciprocate, perhaps if Yukino still had feelings for Nacchan, she would probably "reciprocate" or atleast act like she reciprocates her feelings because now she believes that Nacchan is someone above her.
