The manager whispered, "Let's go back. Judging from the time, Jiang Yu's dance should be over. Since we can't see the actual situation on the stage, we might as well go back and have a good rest."

Li Lu didn't want to go back. She frowned and said unhappily, "Why should we go back? Can't I see what happened to Jiang Yu?"

Her manager also whispered, "But... There's no way to be sure that Jiang Yu will make a fool of herself, right?"

Li Lu didn't say anything. After a long while, she said unhappily, "Let's go back to the lounge."

Her manager was right. If Jiang Yu didn't find a costume for the performance and only had that set of white clothes, she would indeed make a fool of herself. She might not even be able to participate in the competition.
