ALLDAY PROJECT performed their track “FAMOUS.”
During the episode, ALLDAY PROJECT got their first win ten days after debuting.
Ahead of their encore, along with an unexpected interaction between Annie Moon and aespa’s NingNing, netizens couldn’t hide their excitement as Youngseo and Wonhee interacted. Youngseo walked up to Wonhee, going to touch her adorable bangs, which made the ILLIT member smile, before doing a “hwaiting” gesture.
Netizens couldn’t get over the adorable reaction and how natural their interaction was.
