This is just a preview... well it is part of the story, yes, but it is also a preview of what the story will be about.
With all his rage, he targeted the blonde teen-ager in front of him, with almost the same rage the blond striked back—the blonds' hand came against something, has he hit the jet hair kid? And no. All the dirt around, swept away, leaving at the blonds' sight the jet haired boy holding the pink-haired kunoichi.
He analyzed the scene horrified… his hand, his rasengan… his strength; his rage… had just now ended with the life of somebody else. Sakura Haruno.
Sakura stood motionless, the pink-haired girl lying in his arms—the girl breathless. He stared into space, no specific place… he was going to cry, no he couldn't… but he couldn't hold back… the most precious thing for him has now been wiped away. And all because of that stupid blond, standing in front of him.
He could feel the rush of adrenaline coming from his feet to his whole entire body, that blond was going down, he swore he was going down—he was dead already.
Sasuke dropped a few tears over the girls' dead face, and then ordered Suigetsu to take care of Sakura, and finally… he went to where the blond kid was.
-"You killed her..." he pointed (metaphorically speaking) at him… everybody pointed at him… "I'll kill you" Sasuke's eyes burned in anger, the Sharingan was even redder than normal, and his whole chakra seemed overwhelming, overpowering.
Naruto stood motionless… he deserved it, dead. He wasn't fighting it, he was going to die, and he was not fighting for life… he was letting Sasuke kill him… at that right spot, at that right time.
And so, Sasuke was inches away from killing the boy, who got his eyes closed, just in case it hurt. Then this sweet, yet weak voice broke the killing-revengeful atmosphere.
-"Sasuke..." he turned, for a minute, completely forgetting about killing Naruto. Sakura was looking at him; her eyes verily open "Don't..."
