On today's episode of SBS' Strong Heart, TVXQ's Yunho, was a guest along with fellow member Changmin. On the show, Yunho revealed the origin of his stage name. He stated, "My singer / stage name is U-Know Yunho, and it stands for 'you know me and I know you'. To tell you the truth, I thought of the name from an online game I used to play. My username for that game was 'U-Know Yunho'. In the game, I reached the high level of 'supreme', which was right before the highest level of 'God'. Right before I became God, I debuted in TVXQ (Rising Gods Of The East)." It's quite hilarious that we all expect their names to come from some place more meaningful... well, I guess that game was pretty important to Yunho. Source + Photo: Newsen
