See Uchiha's (negative) reaction.

Naruto decided to see how things would go between Sasuke and Sakura. He followed the pinkette to the Uchiha district, careful to stay far enough behind to avoid detection. Sakura ran into her crush and believed lover in front of his house, and he looked annoyed.

"What do you want, Sakura?"

Haruno looked confused and flinched at his cold tone, "I-I told you earlier I would be by, you after we...did it." she said turning red.

"What are you talking about? Why would I have sex with a weakling like you? I need strong wives to restart my clan. But I have to say this is a new low, even for fangirl trash like you. You've been nothing but an increasing annoyance since we met, now get the fuck off my land before I consider you a trespasser and burn you to a crisp."

Sakura was in tears, "B-b-b-but Sask-k-ke-kun, you were m-my f-f-first! W-w-we were supposed to get married and be happy! I love you!"

This is your final warning, GET OFFA MY LAND!" The duck-but head yelled as he began hand signs. Once he had, Sakura took off running, a trail of tears following her.

Naruto watched all this and began to feel bad. Part of him wanted to pound Sasuke for over-reacting like this, but he was also worried Sakura might do something drastic.
