Just a few weeks after being crowned as the inaugural winner of Mnet's Superstar K, Seo In Gook was swiftly reintroduced back on stage, making his solo debut on the 29th October edition of M! Countdown. Looking and sounding good on the stage, Seo In Gook looks like he is on the right track for more success after Superstar K. The performance was done in 2 takes, as the video cuts to another scene at 3:17 where he is joined by a choir of singers as they harmonized to the song. Many thanks to Jae Eun for tip.
