The impact was very subtle if you could it even call it an impact. We were hoping for something more direct but Mio and Nagi sympathized with Sakura, and near the end after pouring their hearts out a bit more to each other they "lightened" Shinobu's "cheating" saying things like how cocky he is and how they'll slug him next time they see him turning it into a joke of sorts so that it weighs less heavily on Sakura going forward. No proof that there is any deeper intent behind this, just thought it an interesting thing to note.
