Easily plays around with Pre-Timeskip Sakura's mind.

"I'm telling you, Sasuke's fine!" Naruto retaliated, pulling away the insistent hand. "He's training! And I have stuff to do!"
Setsuna pulled the obnoxious anger string.
"Like what?" Sakura returned her hands to her hips.
"Like training!" Naruto raised his voice in frustration. "What I've been doing all this time!"
And hanging out with foxgirls, but that's another matter.
"Oh, that's not important; you can do that later!"
"Not important!" Naruto was outraged. "I need to become even stronger to beat that Neji!"
Setsuna's eyes gleamed. There it was: her chance.
She could see it, clearly, in Sakura's mind. Even if the pink-haired girl acknowledged Naruto's growth as a ninja, she still did not believe he could defeat Hyuuga Neji. Apparently, she had been vastly impressed and intimidated by the Hyuuga genius.
Setsuna really had to hold back on a lot of chuckling. It was just too easy.
Take that thought, bring it to the forefront, and expand it. Then, let the girl shape it into words. It was so subtle it might not even deserve to be called "manipulation."
"Ah, come on, like that's gonna make a difference!"
"Fufufu," managed to escape from Setsuna's lips.
Too easy.
