"Due to health issues, Jae will be unable to attend the following schedule on September 6: recording for EBS program 'Space Sympathy'.
We felt that the artist needed rest in order to restore his health, and made the decision regarding his absence; we apologize to fans who were looking forward to this schedule for the sudden news.
If additional schedule changes or conflicts arise, we will relay further notice.
We will do our best toward Jae's quick recovery. Thank you."
Get well soon, Jae!
