Please recommend a good ancient novel with a heart-wrenching plot?

I recommend the following two books to you, both of which are long novels in the ancient language, with BE endings and heartbreaking plots: 1. "I Have a Promise with Spring" told the story of the female protagonist Chun 'er who had come back from the dead. She overcame all kinds of difficulties and tribulations and finally got together with the male protagonist, Gu Jinhan. However, happiness was short-lived. She unfortunately died again, leaving behind an eternal promise. 2. "Xuanji Painting" told the story of the female protagonist, Wen Xin, who sacrificed herself to protect her lover after she was resurrected. Although the ending was very cruel, the description of their love was so affectionate that it made people fantasize about their love. I hope you like my recommendation. Muah ~
