The girls were on stage getting ready to perform but instead of their music coming, SBS had played G-Friend's music. This went on for nearly 30 seconds before SBS had realized their mistake and then played TWICE's music. Although there was a lengthy technical error, the girls did their best, still presenting a great stage. 

Fans were understandably upset and some are demanding an apology from SBS. Netizens commented, "SBS never fails to disappoint me. Freaking idiots. The audio and camera work were horrible too," "Jungyeon's shocked facial expressions was so cute. kekeke but for SBS this year as well," "What a mess of a program," "No wonder I felt something was strange keke," and "... Their facial expressions were like 'WTF?' It was cute though."
