Dress as *************

I feel that the heroine in the book is obviously the princess of Dingguo Palace. Why did she only rely on others without her own guards when the restaurant was threatened by others? Moreover, Liu Ruoli had obviously met the heroine at the banquet, and the outside world also knew that the restaurant was opened by the princess of Dingguo Palace. Why did the heroine lie to her, saying that she was from somewhere else, and gave a false name? I don't understand. Why should the prince be jealous of the heroine? He should always prevent her from opening a restaurant. I feel that the setting is very strange. The heroine is written as if she is a commoner. She is not a young lady from the Dingguo Palace at all. She has no rights at all.
