For anyone who is hating on the main actress: Song Dukim's point of view makes sense. She did not want to be a royal concubine, because she was a woman who clinged to her freedom and her modest life and her friends. Her work as a court servant, which the royal society saw as low work, and that maids had no right to live as they wanted, and she wanted to prove that she was a strong and free woman without anyone, but She was forced to become a royal concubine because she was forced to do so by the king who loved her but did not respect her desire to live the way she always wanted even if she liked him but her feelings were not continuous and sincere and finally she made sure that she was right because her life was not that great As others think, her estrangement from her friends and her son's illness and death destroyed her and led to her illness as well, like the former concubine. โThe palace is a luxurious prisonโ.
