On the wedding night, the bride lifted her hijab herself. "Lu Junxiu, I know you married me for Yang Yuanshu." She took off her wedding dress to her shoulders, and there was a line of words on her shoulders - "May my sister marry a good man." "This is a wish made by my sister. Yang Yuanshu has written it down. Once it is written down, it must be fulfilled." "So you have to help me find her?" "Who?" "My sister's old flame."
