I love this couple as well!! X3 Not cause of Naruhina btw~!! XD
I love'em cause i think sakura's love for sasuke is eternal and even though he's turned badass and tried to kill her!! SHE STILL LOVES HIM!!

Also i think we all know deep down sasuke loves sakura too although he doesn't show it, he just needs someone to take him out off the darkness he's gotten into. I think it's true love! ya know the sayin true love is what makes us stronger!!
