Somebody paid for an ad of IU at the TImes square.
Kpop's most reactionary/most anachronistic/most isolationist singer has significantly changed her position, and is now trying to appeal to the world, despite of her Japanese promotion having gone nowhere in 2012-13.
As she changes her song style to be more palatable to the i-fans, Lee Jieun's Korean fans are increasingly turning back on her, which is why Brave Girls' Rollin is still going strong because the domesticists are now supporting BG, which is unlikely to promote outside of Korea.
IU's haters are also flocking to Laboum, IU's arch enemy. While Laboum is not moving as fast as these people hope for, that is another sign that IU's grip in Korea is weakening
Some people say IU is now old, and will be pushed aside by newer crops. Which I have pointed out for years since she had become a Senior Singer in 2014.
I think that because of the fanatic fans of Brave Girls, Rollin will beat Celebrity at the melon yearly #1 ranking. Many of BG's fans, who didn't know or care who were BG until Viditor had put the fancam, were IU's fans but they have moved to BG because their sounds are more 'Korean'.
For many years IU was the bastion of the domesticists, but when she finally decides to contribute something to KPop after many years of failing to do so, the K-O-R-E-A-N-S are angry and are moving to another domestic act.
