Yes, exactly. You wouldn't believe how many fans still believe Inuyasha loved Kikyo more and only picked Kagome because she was the only one left. That will also probably happen with Sakura, no matter how much evidence we have.
Even though Kiky was a zombie, you must agree that she was still a bigger threat to Inuyasha/Kagome than Sasuke is to NaruSaku.
But yeah, there could never have been a happy end for them, but luckily Inuyasha always loved Kagome more and he's happy.
But the point was in Inuyasha there were mutual romantic feelings
Inuyasha to Kikyo
Kikyo to Inuyasha
Inuyasha to Kagome
Kagome to Inuyasha
and Inuyasha still loved Kikyo after she died the second time. I knew it was going to be KagomexInuyasha but the shippers of KikyoxInuyasha actually had a valid basis for thinking it would end up with their pairing.
In Naruto there's absolutely no valid basis for Sasusaku or Naruhina. Heck the LeeSaku shippers have more validity than either of those and those shippers are polite folks that quietly believe in their ship in a kind of quirky determined way. Because Sakura was actually quite kind to Lee when he was in the hospital, visiting him and leaving him a flower too... and she mentally acknowledged his love for her in the Forest of Death and that added to her motivation to fight and become stronger along with her feelings for Naruto and Sasuke. LeeSaku isn't going to happen, not SaiSaku either (those shippers are around too, and have just as much basis as Naruhina and Sasusaku, but like the LeeSaku shippers they tend to be low key, seen some fanart floating around, and certainly after the confession arc I can see why someone would ship SaiSaku. We can see Sai has come to care about Sakura as deeply as he had Naruto after his introductory arc.)
There's also SasuKar to take into account. Unlike with Sakura, there is some manga canon evidence that Sasuke was attracted to Karin, enough so that she was able to do what only Naruto has done, turn him briefly away from his single-minded hatred of everyone, single-minded plunge into complete darkness. He even says so, using much the same words he uses with Naruto- coldly angry and violent about how they had distracted him. Is it a good relationship- no, not as Sasuke is in part 2, but the feelings were there. And Karin, unlike Sakura did not have an image of Sasuke based on an absolutely false illusion, her attraction was based in reality, what actually happened between them. Karin is a darker more alpha girl than Sakura, much more balanced with him, she routinely argued with him, and made no bones about his more stupid actions- like willingly coming to Orochimaru knowing what he was and what he wanted, instead of her case where Orochimaru found her as a young child, the sole surviving person in a civilian village after bandits slaughtered everyone else... (her ability made her sense the bloodlust coming toward the village and she hid)- a bit of this background was in the manga, but most was from her entry in the third Naruto databook.
Sasuke finds Sakura completely uninteresting in part 1, in part 2 hates her the same as he does all the other people of Konoha, except for Naruto, although he does seem to have gained a minimal respect for her- I think because she did see the threat he really wants to be to the world
Sakura crush on Sasuke in part 1, depressed and ashamed of the remnants of those feelings in part 2. Just don't see any possibility there whatsoever.
Naruto thinks Hinata is a weird, shy girl in part 1 but counts her as a friend, same as he does Lee who he also finds weird. Fights for her because he thinks Neiji acted like a vicious bully, then when he finds out the searing pain that caused Neiji to go the direction he did the fight is no longer about getting back at a bully but waking Neiji up to the fact he still has choices, he's not as caged as he thinks he is. Naruto does this a lot, begins a fight thinking someone is an unforgivable enemy then after hearing their story discovers that person's pain and the fight switches to waking that person up to a different path. Even with Nagato he was able to come to that point, but it took words on both sides not fists to get there. In part 2 he still thinks she's a weird shy girl but counts her as a friend, but has recently come to understand her better-enough to know that all she needs is to realize that she's stronger than she believes she is, is to stop idolizing him and see those qualities in herself. He has never felt anything romantic for her. And Hinata herself looks to be moving on from her part 1- chapter 437 hero worshiping crush on Naruto. In the manga we haven't seen her so much as even lightly blush around him since chapter 450. She was still hero worshiping him, but confusing that with love looks to have faded.
Sasuke may have some romantic feelings for Naruto bound up with hate and the team mate and an intense best friend bond. Kishimoto certainly gives enough of an impression that Sasuke is kind of in love with Naruto that I'm not dismissing the SasuNaru shippers out of hand, but romantically it's still completely one sided so will never happen. Naruto has intense feelings for Sasuke, but on his side it's completely brotherly. The intensity of the mutual bond does give that ship more weight than the other one sided ships- especially sasusaku and naruhina though.
Sakura has semiconscious attraction to Naruto in part 1, and is deeply in love with Naruto in part 2. Naruto is deeply in love with Sakura in parts 1 and 2.
now tell me what pairings have any basis in story reality?
Narusaku: absolute ironclad basis.
SasuKar: something mutual was there, not healthy, but still there. Only plausible ship for Sasuke- if he is redeemed and lives, iffy though even then. Karin will probably be rather wary, and will a redeemed Sasuke even think he should try after what he did to her.
