Ji Yunzhen is Lin Ting's fiancé, arranged by their families. He is concise and formal in his communication, inviting Lin Ting to a charity gala and arranging for a driver to pick her up. He represents the expected path of duty and family obligation, contrasting with Lin Ting's hidden feelings for Lu Hesheng. Ji Yunzhen is not deeply characterized in the text but serves as a plot device to highlight Lin Ting's internal conflict.
