@ciardha Let me rephrase, then. These set-in-stone archetypes that exist in anime do not exist that way in reality. And most people who see someone that is particularly mean to another, for any reason, are not inclined to believe that she will have a dramatic change of heart because of what archetype her personality conforms to. Archetypes are guides by which to write a story, common patterns for common purposes. But how an audience relates to a character is made no more forgivable because of it, especially in a different culture.
Where was Sakura "particularly mean" to Naruto? Nowhere in the manga, in fact quite the opposite, even early on in part 1. Naruto hadn't been particularly loveable to Sakura, and considering his well known reputation as a pranker (the only thing he was known for, other than being a hyperactive, loud mouthed braggart who was basically the polar opposite of what he bragged) Sakura could only take his constant "Sakura chan" in the Academy as mocking her. She says as much in chapter 3 to the henged Naruto. From Viz's official translation- "
If he had his way, I'd never find love
or happiness...he ruins everything...
he enjoys tormenting me! Sakura saying she "hated" Naruto in chapter 4 makes perfect sense if you look at those words.
She believed Naruto was deliberately tormenting her, making a mock of her, and she was seen as very low status by the other girls as it was- the object of tormenting when she started the Academy. Ino's protection only stopped the outright tormenting by the other girls, they still viewed her as lower than them on the day she graduated the Academy (remember in chapter 3, the girls muttering "who does she think she is?!" when she sat down beside Sasuke.) Even Ino, despite her friendship with Sakura still treated Sakura as having a much lower status than herself. We see in chapter 3 Sakura was searching for someone to accept her, and her dream was the boy she crushed on, Sasuke, would. Naruto notes on learning this that he now understands why he likes Sakura, she is searching for the same thing he is. It looks like you misunderstood that Sakura didn't actually "hate" Naruto in chapter 4, she hated what she believed was his deliberate tormenting her, making her a object of Naruto's mocking.
Her chapter 4 words are forgotten by both Naruto and Sakura in the very next chapter. Naruto clearly was intelligent enough to quickly realize that it was Sakura's perception of his behavior that she hated, not himself. Sakura blushes at Naruto's heroics and may be figuring out already that his bragging is just a cover, to not show how afraid he really is. She acts instantly, without a moment's hesitation to do what she can do to save Naruto's life from what she believed was an imminent threat. In Chapter 10, when Zabuza attacks Sakura throws herself on top of Naruto to protect him, no thought about how much in danger she was putting herself in by that action (nor does she think of her crush Sasuke's welfare at this moment,
it's all about saving Naruto from danger. In chapter 11, she realizes she is having some kind of romantic feelings about Naruto- she doesn't react with repulsion, nor even deny it, it just confuses her... Then we have her numerous actions to support or protect Naruto during the Chunin exams, she even defends Naruto to Sasuke and lets Sasuke know in no uncertain terms that she thinks Naruto is a better ninja than Sasuke. This is all in part 1, in part 2 it's her ironclad rule- to be there for Naruto in every way.
That's the polar opposite of the image you were ascribing to Sakura. You stated you judged Sakura because you choose to see her as being like those girls that rejected you. That's not Sakura's character, not even in part 1- one only look at the above examples from manga canon- and look even at how she acted toward Rock Lee in part 1. His out of the blue over the top love at first sight confession creeped her out, but look how she is toward him from that point on- very kindhearted and caring.
