SM Entertainment's girl group, Girls' Generation, had just won their second daesang (Artist of the Year Award), which was the highest honor given to any South Korean artist. And they were the first girl group to win it twice in a row. After celebrating, the girls were told that they were to debut in japan . . . . 

(Readers: most of the info r true, or an assumption by me so vips, sones, and johnny boy fans don't get jealous xD)
