Girls' Generationcontinues to pump out more teaser content for'Holiday Night', this time featuring memberSunny."I remember every bit of our debut stage. Everyone didn't know what was going on and we were very nervous too. We have all come a long way and we were able to make it because we enjoyed the ride. If I were to go back to that time again, I don't think I would necessarily try to change anything."
