Have you seen HyunA's performance, After School's pole dance, or, most recently, Girls' Day's new dresses?

Even when groups are restricted from broadcasting their performances on major TV channels because of their provocative performances, it is not a major controversy, which says a lot about our current k-pop culture and the public's awareness of girl groups.

The point is exactly that how much sex appeal a singer can give to the audience. Although not scientifically proven, the longevity of one's life as a singer depends on the sex appeal, regardless of the gender.

One girl group, who surprised a lot of people with their sexy performance on stage, told a reporter, "We want our performance to be controversial because of the provocative nature, so that it can be a hot issue." Their performance did not rise as a hot issue. However, when it does, it is an explosive success. The reason why all girl groups who are naïve and cheerful in the beginning all become sexy groups is because they cannot survive in the k-pop market otherwise.
