Late at night, at a top jewelry auction, Gu Qingyue, the president of the Gu Group, held up a placard to highlight the collection. Under the spotlight, she accidentally caught a glimpse of a birthmark on the back of a waiter's neck - exactly the same as her sister who had been missing for twenty years. The waiter was being made difficult by the rich daughter, and a glass of red wine was thrown in his face. Gu Qingyue grabbed the microphone and her voice echoed throughout the audience: "Who dares to touch my sister, Gu Qingyue?"
