Brave Girls will be releasing the new version of their hit song "Rollin'" in just a few hours on August 11 at 6 PM KST; however, it's been ultimately revealed that Hayun did not participate in the new single.

According to Brave Entertainment, Hayun was unable to participate in the new version of "Rollin'" due to health issues. As a result, Brave Girls plan on promoting as a group of 4 for the time being.

Previously, when fans spotted only 4 Brave Girls members in their "Rollin'" MV teaser, they began wondering where Hayun was. We hope Hayun can recover soon.
