AN: Rewrote the Prologue so it made more sense.
Prologue
Once upon a time there lived a young boy, Sasuke, with a very powerful family. The Uchiha clan was a very well known one. But one day, Sasuke returned home from school to find his whole clan massacred by none other than his older brother, Itachi. This turned the boy into a very cold and uncaring person. One man, Orochimaru, decided that it would be fun to mess with the boy and placed a curse on him. Now whenever Sasuke would mold chakra it would go out of control, causing him to use more than he would like. At first it hurt whenever he'd mold chakra, but soon Sasuke got used to the extreme power it provided him with. He began thinking that it was the best way to take his revenge on his brother for killing off their entire clan.
Then one day the man who had cursed him reappeared and explained that each time that power is activated some of his life gets taken from him. This of course angered Sasuke because he was still an avenger. What he did not know though was that the only cure for this curse was to fall in love and for that person to love him back. Orochimaru knew this was the perfect curse for him because with Sasuke's cold and uncaring personality, it would never happen. He would be cursed forever.
