Naruto and Sasuke when they were younger, Sasuke made a promise to Naru to marry him when they get older.
But Sasu was born as a prince, while Naru wasn't.
(Uh... Naru is 5 years old, and Sasu is 6 years old. BTW!! NARUTO IS A GUY!!!!! NOT A GIRL IN THE STORY!!)
As the tale goes, Sasu got separated from Naru, because he need to go to the kingdom and education and see how the kingdom works.
*Ten years later*
Now, Sasuke is going to be king but needs a wife.
