My answer might be a little inaccurate. According to the information you provided, I understand that you want an ancient novel in which the female protagonist is caught by the male protagonist and put on a golden anklet for the female protagonist. I can recommend a novel like this to you called 'Feng Qiuhuang.' The novel was a time-travel novel. It told the story of the female lead, Chu Yu, who had traveled to ancient times and became an imprisoned empress. During the period of being trapped, the emotional entanglement and conspiracy between her and the emperor were inseparable. The male protagonist of the novel was an emperor named Zhao Su. He took advantage of Chu Yu's weakness to control her. The novel had a strong sense of feudal society and also involved some love and conspiracy topics. I hope you will like this book.
