I do believe Kishi is near completing a closure for SS. I start to believe it when Sakura fake smiled. Why is it significant? Because if Kishi wanted to make SS a redemption pairing, Sasuke would be in his way to do so, but he doesn't care at all and he still wants Naruto dead. So why 540 happened? Because based on now, we are witnessing her becoming incredibly doubtful to her feelings for Sasuke as it grows more negative than ever. Like is this the guy you can live with as a lover? 540 was the first time that her love was questioned and it was negative.
Yeah i know what you mean , ive never seen her givin SAsuke those looks:
or that.
So, yeah its pretty obvious who she loves , but then again why did kishi made 540 i still kind of ambigious many fans say that is her conformation of her love and she didnt tought of Naruto at all and such , but knowing kishi he will work it out.. :)
To add more damage, Kishi seems ready to change her feelings because NS keeps growing as Naruto keeps impressing her and she even back him up. Minato pretty much sealed it because it will be unnecessary to make this irrelevant. Yes, they're not together yet but stuff like this you can't back away. So pretty much, we are at the peak that her love for Sasuke is truly fading. Her love was finally brought up in the last arc so it's no wonder all this turmoil is happening now. Ino seems done with Sasuke but we'll see. Anyway, yeah, we are almost home.
