That's great, I watched the performance. I think this is their second best performance of Sugar Free after last week's Inkigayo. Each performance has different outfits, stage, and camera angles. The members performed well, I think they had a good day today. The camera angles were exciting.
I believe they have performed here so far:
140911 KBS 2014 17th Incheon Asian Games
140911 Mnet M! Countdown
140912 KBS Music Bank
140913 MBC Music Core
