At yesterday’s concert, Jieun’s IU wasn’t serious, but there was a situation where I couldn’t control my ears since a year ago I told them that I needed to do well on the day of the concert, and that my ears were okay They say it’s nothing serious, but it’s really fatal for a singer to have difficulty controlling his ears I’m worried that it’s been a year or so I’m not worried about celebrities, but in this case, I can’t help but worry
