'Wait, how come Wanna One has 12 members?'

Toward the end of the '2017 SBS Gayo Daejeon' aired on December 25, all of the K-Pop artists in attendance, including WINNER and Wanna One, stood on stage once again to greet the audience for the final time.

In the midst of the artists taking selcas, waving to the audience, and more, fans filmed Kang Seung Yoon walking toward the stage with his group WINNER, along with Wanna One ahead of them. But he somehow caught up with the 11-member group and was about to bow with the rest of the boys, when he realized he was with the wrong bunch.

Realizing this, Kang Seung Yoon froze in his tracks and quickly scrambled over to his group, looking rather embarrassed.

Netizens commented, "His swift reaction is so adorable", "It's hilarious how his dazed expression is plainly caught on camera", and such.
