One of the standout entries belonged to Kim Eun Joo, who managed to wow the judges with her perfect pitch and powerful personality.

Yang Hyun Suk was surprised at her lack of in-ear earphones, saying that it would have been near impossible for her to begin singing on key, especially considering that she had begun singing even before the backing track had begun. 

Kim Eun Joo also revealed that she had no prior singing experience. J.Y. Park praised her versatility, saying that she already knew proper singing technique.

The contestant successfully moved on to the next round, giving viewers something to anticipate the next time she stands on stage.
