at 0:39 you can also see she's not bending her knee in close to her body either. she's definitely injured and has another concert today and then the japan one in a couple of days... really worried about her
people say twice cant dance or thier dances are easy they forget they are 9 girls who move in perfect sync with the other 8 to be at a certain spot at a certain moment only to have to move again a few notes late all they see is the chorus choreography from title tracks but those those are done specificly for once so they can learn and dance along with the music
TheWhizard h i find out thats there two video about this performance and in each video sana actually doing a different gesture at her part so i was thinking could they have perform "touchdown"twice
