Having successfully pointed out the person who couldn't carry a tune in the first round, Roy Kim commented, "I have never lip-synced a performance."

With that, the MCs asked, "What happens if your voice isn't in good condition?" �The singer then replied, "I just wing it even if my voice is in bad condition," presenting his professionalism.

Following this, he gave a special performance, you guessed it, lip-syncing a song for the very first time. �Holding up a large boom mic, Roy Kim "sang" his heart out while making exaggerated facial expressions and gestures, causing the studio to go wild.
