Re: Just a thought and what if's
Even with Kishi's weird antics when it comes to character development and springing things out of the air, the way Kishi wrote Sakura she simply doesn't have that kind of emotional motivation, even if your fan story where true. Just look at Kishi's strongest female characters and how poorly written they have been made out to be.
