Xiao Longnu and Gongsun Zhi had a wonderful time together, but Gongsun Zhi was heartless to her and even hurt her and her family. According to the novel, Gong Sunzhi was a very cold and heartless person. He had no feelings for his family and friends and would only act for his own benefit. He did not care about Xiao Longnu at all, and even used her to achieve his goals. Therefore, Xiao Longnu did not know how heartless Gongsun Zhi was. This was probably one of the reasons why they could no longer be together. Although Gongsun Zhi's behavior was very painful, Xiao Longnu finally chose to leave him to find her own happiness.
