"Sakura smiling doesn't mean anything, it certainly doesn't confirm that she will agree to wath over him"
"Minato said to be gentle on his son after Sakura headbutted him, obviously he was being literal and Sakura will try not to hit him in front of Minato anymore"
"Minato doesn't approve of NS at all his reaction and sweat drop confirm this"
"Sakura smiling doesn't mean she's agreeing to take care of Naruto, if she was she would be blushing"
"Sakura was smiling at Minato's words but her curved eyebrows with her facial expression shows that she will take care of him but only as a friend the only thing that's missing is the "awkward sweat drop" If Sakura did like Naruto she wouldn't headbutt him for confirming their relationship"
and the rest is mostly directed at 540 "He's a close dear friend but she just doesn't like him in that way" blah blah blah
