The original lyrics was different but the night before recording day, Angelina Jolie appeared in Jaejoong’s dream.
Here is what happened in his dream:
Angelina Jolie was flying with black wings like in the movie (Thing is, before this dream, Jaejoong hasn’t watched this movie, he didn’t even know that it was already shown at box office)
She told Jaejoong, “I’ll teach you how to fly.” Then she picked him up and flied to the sky (Jaejoong said Angelina Jolie talked to him in Korean LOL)
After that he was flying like Peter Pan LOL.
So, after waking up, he wrote the lyrics basing on the story of Angelina Jolie and Brad Pitt.
Yoochun and Junsu said they didn’t know at all. They thought J in is Jaejoong.
Jaejoong said actually he didn’t want to disclose this story. If Angelina Jolie knows, she might not be happy about it LOL.
