Contrary to popular belief, Naruto liked reading. He liked reading things with a plot, action, and maybe a little romance. He liked reading things that made him think (and yes, contrary to popular belief, Naruto ALSO liked thinking.)
That's right, Naruto liked reading good books.
That was why Naruto couldn't possibly fathom why he even bothered to read the pointless nonsense that spewed forth from Sakura's mind and onto paper.
Sasuke is gorgeous
Sasuke+ Sakura 4eva!
Mrs. Uchiha…
… and all this wonderfully colourful bullshit was surrounded my many, many love hearts.
It was amazing, really, the amount of ways you could pretend to be devoted to one person. Naruto knew she was pretending though, after all, she was just a silly little girl, she didn't know what it was like. To just know that one person was just meant for you.
Ino's scribbles were even more incredible:
Sasuke is my drug
Sasuke is the greatest
I want to have Sasuke's babies. (Naruto raised an eyebrow at this one).
While the statements themselves were truly fascinating, what was even more incredible is that there were even more love hearts on Ino's "artwork" than on Sakura's. And for that reason, he thought her even sillier than Sakura. Didn't they know that hearts could break?
Naruto figured that he could go through the notebooks of every girl in the village and find the same sort of crap over and over again, but frankly, he didn't have time for that many love hearts.
What Naruto liked reading was his own handiwork. A single line of writing, and though no one else would see it the way he did, it was truly a masterpiece to him. It wasn't anything special, just words, and no one but Naruto would ever read them either.
Sure there were no hearts surrounding it, and the writing itself was terrible. But it spoke a truth that no one else could take away. It was a statement, a fact, because Naruto wasn't a silly girl, he wasn't pretending. What Naruto wrote was different, it simply said:
I love him.
