Takes place during episode 206 of Shippuden.
Sakura imagines a nice life as she walks. A normal life. No passion, but loving nonetheless. The further she walks, the more resolved she is. Hinata will get over it. Sasuke will never know. Naruto will be elated. He won't know it's a lie. And she's certain she'll convince herself over time. They'll have one child, as all shinobi do in case of wartime, and send it to the academy. She'll retire from missions when they have their child, maybe she'll teach medical ninjutsu.
And, blessedly, Naruto will be alive. The village will still have their hero jinchūriki, and he will be safe from the Akatsuki.
She admonishes herself as she grows closer to her destination for her inner turmoil. In truth, anyone would be lucky to be with Naruto. She is no martyr for accepting the love of the hero of the village. It shouldn't feel like such a sacrifice to forsake someone who forsook her long ago.
So she approaches him, with the word whore briefly coming to mind as she begins to lie. But Naruto isn't as dumb as he used to be, and frankly she's shocked that she could have miscalculated so profoundly. She wants him to come back to the village, she wants her love to be enough to convince him. Tears well in her eyes as she remembers the last time she tried to convince someone to turn around and go back to the village. Her love hadn't been enough then, either. This time, she will be the one to leave. She turns on her heel, stung by rejection, and marches away. She knows what she must do now. Sakura will not again make the mistake of thinking her love alone is enough to change anything. But her Will of Fire sure as hell will be.
