You're parents and their parents are close friends. You are two years younger than Sasuke. He is ten years old, and you're eight. Then there is Itachi, his older brother, who is fifteen. You three were not really the best of friends.

Your parents and theirs had a meeting to go too, so your parents left you at Sasuke and Itachi's parents house. You were left alone in that house with Sasuke and Itachi.
