The atmosphere in the Yu Family had been very tense recently. Their youngest daughter, Yu Yao, who had been missing for many years and had just been found, had fallen into a coma for some unknown reason.
The doctor could not find any external problems, so they invited the world's most famous psychologist. The specialist faced Yu Yao, who was in a coma, and felt that this case was very tricky. He could not communicate with Yu Yao, so he could use other methods.
The psychologist asked the Yu family many questions about Yu Yao. Based on the information he got from the Yu family, he could only conclude that Yu Yao had dual personalities.
As for the reason why she was unconscious, it might be due to the revival of the primary personality or the fusion of the two personalities.
