During this week's airing of 'Masked King
,' yet another talented idol vocalist appeared on the show, drawing much interest in his identity!
Performing under the alias, Well Blewup Wi-Fi, BTOB's Changsub's identity was revealed only after the second round where he lost to Small Drunk Tiger by 9 points.
On this day, Changsub sang "You Inside My Memories" by Hwang Chi Hoon, receiving positive feedback from the judges for his flawless stage performance despite the difficult beats of the song.
However, after being revealed of his identity, Changsub showed disappointment in not being able to surpass Sungjae during his appearance on the show.
He said, "They've been telling me that I am a lead vocalist (in BTOB). But since Sungjae got to the third round in 'Masked King,' I think I am going to become a sub-sub-sub-sub vocalist."
