Late August, SM Entertainment announced Kyuhyun would be taking a short hiatus to recover from vocal chord nodules. It appears the singer is now healthy enough to return to his activities. SME stated on September 6, "Kyuhyun has gotten enough rest. As long as nothing goes wrong, he'll be filming for 'Radio Star' on the 21st."
BTOB's Sungjae and comedian Yang Sae Hyung have been filling in for Kyuhyun in the meantime.
Are you excited for Kyuhyun's return to 'Radio Star'?
