Two days ago this?", "Other members were also in bad physical conditions, but still on the stage ...", "Sulli's bad physical condition really?" "eventhough she was in bad condition, she could take a picture! Don't blame her!", "we do not know when the photo was taken exactly!", "could harm the image of her!".
