Is it just me or Tiffany really did a mistake during Check performance? I watched back this video when they performed at music bank and Tiffany danced differently from the other members. When she's in the middle singing "my only one man" they supposed to be facing to the right first then left but Tiffany did it differently. I've watched their other Check performance during Banyan Tree Comback Showcase and she did correctly so I guess, she forgot the choreography for a second hahaha. But I think that's a cute mistake hahaha =D

Thank you so much for sharing these.
