It's oddly remarkable how things in life work. Like coincidences, for example.
A mind-boggling example of a coincidence would be that two brothers from the exact same clan from the exact same town were outside on the exact same night at the exact same time looking at the exact same shooting star wishing the exact same thing at the exact same time.
I wish I didn't have to live with myself.
The oldest, Itachi, had a difficult fact to live with. He had been ordered by the Hokage to kill his entire clan, since his father was planning to take over Konoha with the rest of the Uchiha clan. Itachi was hated by everyone, and he was tired. The only person he couldn't bring himself to bring was his little brother, Sasuke. How could he? He cared more about Sasuke than anyone. Every day, he thought of Sasuke, and waited for the day that he would avenge the clan by killing him.
Was Sasuke strong enough to face Itachi? He had no idea- the only way to tell was to wait. So, every day, he did just that. Waited for his brother to end his life.
The youngest, Sasuke, on the other hand, was simply angry. Why Itachi had killed his clan, he had no idea why. Why Itachi had kept him alive to suffer, he also had no idea why. He wanted nothing but to avenge his clan by killing his brother in a most painful way. But where was he? It seemed like every time he got closer to Itachi, he would disappear. He was always one step ahead of him, and Sasuke would have to track him down over and over again.
Sasuke hated everything and everyone. He hated Konoha, his best friends, his sensei, and, most of all, Itachi. When would he find him and avenge his family? Was he strong enough? His future held nothing but questions. He was filled with anger and regret. Regret that he was never able to stop Itachi.
At the exact same time, the two thought about how stupid this was- wishing on a shooting star? Two brothers, complete enemies, both rogue criminals, wishing on a shooting star. They couldn't help but smirk as they both thought this.
It's very amazing how it all worked. They had done everything at the same time. Not one second off. Not even a half second off. Not anything off.
Little did they know that night, that moment, would change their lives forever.
