Naruto
Here, Sakura, after meeting Naruko, realizes that Sasuke is not so interesting, what is there in him besides a pretty face and a clan? Nothing, so Sakura realized it, thought, thought, realized that she didn't want to be friends with Ino again, and started being friends with Naruko.
• They became friends a year before the academy.*
• Sakura often disappears into Naruko's apartment, and the money her parents give her for pocket expenses is spent on furnishing the apartment (she was in good shape anyway, but Sakura felt that this was not enough).
• Sakura has long hair, and she puts it in a high ponytail. Naruko has long hair, but she can't take care of it properly.
• Sometimes Sakura helps Naruko with washing her hair. And in general, sometimes they take a bath together.
• Sakura's parents know that she's with a friend, but they don't know who that friend is.
• At the academy, Sakura is the best in theory, and slightly above average in practice. Naruko is average in theory, and the best in practice.
• Sakura and Naruko train together, which is why their teamwork is excellent.
• Sakura decided to become a doctor because Naruko heals like a dog, and she has to recover for several days.
• Naruko is not familiar with Konohomaru, and has not encountered Gaara.
• After Orochimaru's attack in the forest, Naruko was lost to the society of "what a beautiful, and what a language", Sakura knew that something like this would happen one day, so she just looked at this circus, and Sasuke began to shudder every time Naruko sighed noisily.
• After the mission to find Tsunade, Sakura realized that Naruko would leave soon, and decided to leave with her (Sasuke went to Orochimaru for power, Naruko just found an object to sigh at, and Sakura just can't imagine her life without Naruko (not peering), so Team 7 dumped Orochimaru).
• From Orochimaru, Naruko began to study fuin, the basics of medicine, poisons, and futon. Sakura medicine, poisons, suiton.
• Sasuke didn't kill Orochimaru, he's not crazy enough to kill the "victim" of Uzumaki's love.
• Naruko and Sakura stay with Orochimaru instead of leaving with Sasuke.
• Orochimaru is amused by how Naruko tries to take care of him, but he doesn't mind, and sometimes he pays attention.
• Naruko has a snake summoning, Sakura has someone who understands medicine.
* - Let the Shinobi academy start at 7, not 6, before that it's just something like a preparatory class.
° You can make Sakura agree to give birth and raise a child from Sasuke, and after graduation, transfer her/him to Sasuke. But there is no love between them, maximum mutual respect.
° Naruko does not become hokage. The Hokage is still Kakashi.
° You can bring Sakura and Kabuto together, or Sakura and Karin.
