Wheesung is ready to claim the stage once again with his new song, "They Are Coming"! Many were looking forward to his comeback performance on 'M Countdown', but unfortunately, Wheesung was unable to give a live performance due to an ulcer that prevented him from singing his best. As such, he decided to lip-sync the performance of "They Are Coming" today to conserve his strength. "UUU", on the other hand, Wheesung did manage to sing live. In any case, he certainly managed to drive the ladies wild with his swagger. Check out his performances below!
