Kayle that just arrived found Sakura's reaction slightly strange but didn't question it more than this.
Kayle: "Of course I know about Sasuke he was obsessed with winning against me all the time, as for Sakura? nice to meet you, we didn't get to interact much, as I only talk to two or three girls from the Academy, all my other aquaintances are mostly boys"
Sakura: "Oh you were close to a few girls from the Academy? who were they? I might know them"
Kayle: "Oh It's mainly Hinata, Ino, and tenten"
Sakura got slightly flustered hearing that he knew about Ino, she never really cared about neither Hinata nor Tenten, they were both well below her in terms of both looks or personality and she really wasn't close to them either way, but Ino was a different story.
Since little, she always admired her for her look and felt a little jealous of her, she also had a great personality as she was the first one that came towards her and accepted her as her friend letting her play with everyone when they were little... they friendship got a little complicated as it turned out into rivalry and now she just learned Ino had once more a step ahead of her.
Sakura: "Ino? how do you know her?"
Kayle: "Oh I spent quite some time in their follower shop! I really love that place, so I got to know her for several years and as we played together often we got very close"
Sakura: "...Well, I really consider Ino as my best friend! we two are like sisters.. and I'd hate to say it but you have to be careful around her... She likes to talk behind someone's back... please don't hate her for it... it's just her personality is like that, she doesn't mean bad"
Kayle: '... isn't that what she is doing right now? well whatever
Kayle: "Thanks for the advice I will take note of it"
Sasuke had been silent and was trying to gauge Kayle finally reached his patience's limit.
Sasuke: "Sakura? Stop annoying us with silly questions? I want to know how Kayle could get this strong"
Sakura pouted but didn't say anything, Even if she recently got a little crush for Kayle she still feelings for Sasuke and didn't want to upset him either.
Kayle: "Well the is no magical secret, the Key is persistent training, and doing smartly"
Sasuke: "I've been training every day! so why would our difference be so big?"
Kayle: "You can't have trained more than me... that's impossible, but even if you did have a similar quantity of training the quality of mine would be better, I since young had several Jonins friends who taught me what I wanted"
Sasuke nodded, he had been lonely all this time as he wanted to have a calm and private space for his training, but now that Kayle was mentioning it, except the teachers in the Academy, and Kakashi that he met not too long ago, he didn't have anyone who could advise him and guide him.
Sasuke: 'It seems like I will have to rely on Kakashi-sensei, for now, to seed up my progress or else I would never catch up to my objective'
Naruto didn't understand everything Kayle said and didn't really need to do that, he was convinced that with enough training he would become Hokage, so all he had to do was to keep being persistent.
The next few days went without any accident, and there was no big difference from the original story, the only thing that changed was Sasuke unlocking his second tomoe which helped him succeed in the tree climbing slightly faster than Naruto.
