[소통] Why is this so funny? Woo Seok, you don't recognize Kim Soo Hyun

At the AAA awards ceremony held last time

Woo Seok won the award for the song Eclipse Sonagi, but Suhyun didn't know that Ryu Seonjae was Woo Seok.

Why is this scene like this when people are clapping and cheering?

Is it funny? LOL
