Even though he’s been at the top all the time, he still bows to everyone very politely. Actually, there’s a reason for it. According to people in SM Entertainment, Yunho always says he could achieve such a great success thanks to great help from people around him. Yeah, he is not a maverick and is the one who can be thankful to people around him for their help. People in the k-pop world agree that he is modest by nature and is not the type of person who puts on airs, while the upright veteran idol star has been setting a good example to young and fresh k-pop idols.
