On the November 30 episode, Seo Yeh Ahn particularly had the viewers and judges entertained with her cover of Ariane Grande's "Problem". Seo Yeh Ahn hit the notes, but it's her awkward sounds and flailing that got people reacting, laughing, and even had judge J.Y. Park crying. Her random "WOO!" and her embarrassed, "Aigoo, thank you," at the end made her an unintentionally adorable performer.

Prior to the performance, Seo Yeh Ahn states in the video at the 0:18 mark, "Honestly, when I go up on the stage, I don't remember well what happened on the stage." She continues, "Although I don't completely transform [into a different person], I'm not as quiet like [how I usually am] either."

Whatever's happening on stage, the judges are loving it. J.Y. Park signed up to be Seo Yeh Ahn's first fanboy, saying, "I like a girl who dances like this. You got my preference. Even if there was a girl dancing well next to you I think my eyes would go to you. I think it would be good for your next performance to perform a song with soul. Your voice is that of a singer of this generation."

Judge Yoo Hee Yeol added, "It feels like we've discovered a new era of our nation's dance music. It's possible [your] video will gain 1 million hits. Next time I want to see you again. Never take dance lessons."

"Never take dance lessons." Pro advice, and considering that her "bad dancing" is her charm right now, I second it!
