Always with the moon.
Everything starts and ends with the moon. The moon is Sasuke; gloomy and silent; mysterious and cold. Of course the moon can never be alone, sure some nights it looks lonely in the endless black sky but you have to remember that the moon has all those stars surrounding it... making it look more beautiful.
Those stars are like Sasuke's fan club. Forever surrounding him, complementing him and showing everyone who passes by, that he was someone to remember and admire.
Then there's the sun. Every time someone thinks about that floating ball of fire it's not what you'd expect. Sure we think of how nice and warm it feels on our skin, but then...
You can't gaze at the sun like you can the moon; and that's annoying. The extreme bright rays make you drop your gaze to the ground and grimace.
Naruto's like the sun. Bright and cheerful; loud and annoying... and you never notice it, but the sun is all alone in its sky. Many days there are clouds, but they're always rolling by as if trying to get away.
Those clouds are like Naruto's whole world, alone with everyone in the crowd. Everyone rushing past him, and like the birds that fly in the sky, those close keep a good distance, so as not to be burned.
And like the two, they're complete opposites. One openly admired by all. The other tolerated by the selected few. One silent and morbid; tuning the world out. While the other is loud, colorful and brash, always silently pleading for attention...
There is also the first time they met. When they actually acknowledged one another.
During that one fateful sunset they both saw one another.
As the moon rose into the sky, stained beautifully with red as if washed over with tears of frustration, Sasuke saw, for the first time how sad and lonely Naruto was. He saw that fiery beauty – and he wanted it.
Naruto finally noticed Sasuke's heart that beginning night, he saw the heavenly glow around the boy that screamed seduction – and he wanted it, but with the fear in his heart, much like the sun as it finished it's silent anguish song, he left.
That was when Sasuke realized-
He had to give Naruto a reason to shine with love and comfort. After all, he was the moon reincarnated. No one could resist his charms.

Right?
