During MAMA press conference, Leeteuk was asked what is needed for Hallyu Wave to continue. He said, "with the start of Hallyu wave, we are performing in Europe and Japan. When I look at the price of a concert ticket, I'm worried that it might have an adverse effect. If concerts are produced with great systems, it's not a problem. However, if many people only chase after profits, number of Kpop fans will dwindle. I hope people focus on promoting songs and performances instead." Wise words from Leeteuk.
