This is the song from the album "the..." of JYJ, they released this album Sep. 2010 , their live was in Tokyo dome and A-nation, I love this song live more than recording and add the english sub for who don't know the japanese, but you know japanese and english are very different types of language in so many ways(on the other hand japanese and korean are much similar) so I tried hard to translate those implicative meanings between the line of lyrics more smoothly from Japanese to English, however still not perfect enjoy the song anyway..
