In order to regain the manuscript and save his mother, Wen Zhiyu imitated the portrait in Li Chengyuan's study and touched the porcelain. He wanted to be a substitute for a backer, but he didn't know that she was the fiancée he was looking for. A misunderstanding breaks out, he humiliates her and puts her under house arrest, and she escapes in despair by pretending to die. Until he found the fragments of the destroyed letter asking for help, Li Chengyuan went completely crazy. After finding her, he knelt down in public: "Zhiyu, I kneel down and beg you to turn back. I will be at your disposal for the rest of my life."
