I recommend Begonia Drunken Rouge. This ancient romance-classical fictional novel described the female protagonist's family being destroyed by an accident. Later, she was forced to enter the palace for revenge. During this period, she also met her good friend who entered the palace to be a concubine. It matched the plot. At the same time, this book also covered elements such as drama, palace fights, and power schemes. I hope you like my recommendation. Muah!
