I think since so many people helped her realize her growing feelings for naruto already, Kishi might have her realize she loves him on her own. Cause Yamato, Sai, Kakashi, and Minato, have already given us the impression she loves him and most named have given Sakura the idea that they are more than just friends, so Sakura realizing it on her own this time, is most likely how Kishi plans on doing it.
It so happened that all of them are said in their mind and if not, interrupted. It's like "What's keeping it so long?" I don't know what's exactly is Kishi plotting with the recent events, but it's no secret that SS is displayed highly negative, while secretly or so has Kishi tried to be, NS is gaining huge momentum. Many have start to think perhaps Kakashi is right but Sakura don't know. It's possible but I wouldn't know if it's right. All I know SS moments in here are displayed negative for unknown reasons, and NS is continue to play as more than friends, let alone best friends.
