look at the 1:11 part (first chorus), I think Yuri did a wrong dance step and Sunny on her back started to confuse also on her step because of Yuri. Hahahahaha so cute :-D
See people I've been trying to tell you that Sunny didn't make a mistake in the mv because everyone had their own timing with the move at 2:14. They all came up at a different time from that head dip. Now we see it clear as day. Thanks for this fancam it's amazing.
Regina Astyn Bagay She's injuried both her knees had surgery and everything so she's being super careful because one wrong/careless move and she'll be in a world of more pain.
