Won’t you say something….?
I truly believe Sakura is a strong woman for her hardships and i can't see anyone else helping Sasuke through his hardship and loneliness then her. Sure Naruto was his brother and he knew Naruto would be there for him but he also deserved a happy ending like Naruto, that was the thing between the Sons of the Sage Six Paths. One had something while the other didn't but this time not only they both have powers to now protect others but both found happiness in their lives.
