@Hessa, neither there is anything about a curse and prophecy mentioned anywhere... well, of course, the language barrier works its evil work, as, when I read about him in Wikipedia and turn the page to the Korean article, then traslate it through Google translate, I am still guessing half the text. But again, nothing about exile, prophecy or that he was unloved in the family. Quite opposite, actually, it says, because of his bold personality he was quite loved by the king (though I couldn't decifer anything about the Queen) :P
