Did the author try to deceive fans who preferred the 'Narusaku' relationship, instead of developing the 'NaruHina' couple? If this was indeed Kishimoto's intention, I find that he is much worse at developing romance than I had imagined. I believe he attempted to emulate romantic elements from 'Slam Dunk', but in the end, he seemed to adopt the approach of 'Akira', where unexpected couples were formed at the conclusion of the work.An example of a couple that surprised many was Vegeta and Bulma, which became quite popular, unlike Sasuke-Sakura and Naruto-Hinata, which grew less and less popular. If he wanted to avoid scrutiny, it would have been simpler for him to not explicitly demonstrate the protagonist's feelings, as was the case in 'Bleach'. However, even this approach had its complications for the author.
No, Kishimoto wasn't trying to gaslight anyone. The quote that I posted is just the desperate, self-deceptive rationale that NaruHina fans clutch to because acknowledging the alternative - that it only came about because he was forced -, is too bitter a truth to accept. He's stated in the past that he doesn't understand Hinata's appeal and that he resisted when people tried to convince him to replace Sakura with her as the lead heroine. Add to that, he confirmed that Sakura's confession to Naruto was genuine, to say nothing of the numerous parallels that he's drawn between between them and other relationships in the series. (Rin/Obito, Jiraiya/Tsunade, Sakura's parents as well as his own)
Then you have his father directly comparing Sakura to his wife, Naruto introducing her as his girlfriend (with her not even denying it), saving Naruto with the Kiss of Life, etc. You don't put that much ridiculous effort into structuring and developing a relationship with a clearly romantic tint for hundreds of chapters, just to go "Psyche! The real heroine/love interest is the side character chick who contributes absolutely nothing to the overall series and barely interacts with the protagonist because boobs and men love submissive females! Kakakakaka!" He wasn't even involved with the Last aside from the movie novelization and there, he illustrated that Naruto's feelings for Hinata were out of obligation for not realizing that she was in love with him. Dude has even gone on record of saying that the NaruHina couple is "born out of pity for Hinata".
And if NaruHina was planned, then he wouldn't go out of his way to show how dysfunctional their family dynamic is or how miserable and negligent Naruto himself is as both a husband and father.
