The issue started from Sooyoung's bracelet when they danced to Dumb Dumb...
It was hitting really hard on her hand when she was dancing... It must have been so painful
She removed it right away when the song ended.
And prepared for the remaining stages
And when the stages ended, she picked it up and left...
I like Joy so muchㅠㅠㅠㅠ
