You know it's funny the only NaruSaku interaction we got was this, and it was Post-The Last , Pre-Gaiden. Actually from the Sakura novel.
She heard that Naruto started teaching at the academy from time to time as a special lecturer after the Great War. And watching him now, he seemed to be doing an excellent job of it. "Hey! When you're sparring, make sure you weave the sign of reconciliation! whether you're strong or weak or whatever, that's a ninja rule."
Students who did not follow the kata etiquette got a rap on the head from Naruto.
You were like that too, way back when, Sakura told him in her head and smiled softly.
Once he ha given instruction to all the students, Naruto had them line up and bowed with him.
Raising his head, he noticed Sakura. "Hey!" he called out. "Sakura!"
She waved her hand in a small gesture.
"You guys just wait a sec," Naruto told the children before trotting over to her, "What's up? You got the day off?"
"Mmm, well I guess it's something like that," Sakura answered. "But look at you, you're quite the teacher , hmm"
"Right?" Naruto grinned and rubbed the bottom of his nose with a finger. He then clapped his hands together. "Oh, hey! You're here now, why don't you give it a go too? teach them their kata."
"What? No, I'm good."
"Come on, just for a minute. Show them the incredible techniques of a lady ninja with superhuman strength!"
"Now look, you can just stop with the 'superhuman thing-"
"Hey! Guys! A super amazing guest teacher's come by you today!" Naruto turned to the children and shouted, and without a sparing second for Sakura's protest. "Check it out! Superhuman lady ninja teacher, Haruno Sakura!"
"And now you say it a second time!" Just as Sakura shot off this retort, the children joined their voices as one.
"Thank you very much, superhuman teacher!"
"See? This is because you shoot your mouth off!" Sakura said with a snort.
"Hurry up!" he called, returning to the children.
"This guy..." Sakura said to him in her mind, and briefly smiled.
Everything I written was word for word from the novel,, and I remember making a post about another moment that happens shortly afterwards too from the Sakura Novel.
Sarada only worked because she is a full female Sauce with neither Sakura's hair or eye color. In fact, she did not resemble Sakura at all to the point where (if you add in Sarada's glasses) Sakura being her birth mother was questionable. Hence why the Karin hints and the gaiden existed in the first place. 
Am I wrong?
