It's time for another political marriage between Xin Plains and Mo Plains. According to custom, the princess of Xin Plains has to be married to Mo Plains. Plains Madam and Yin Song are not willing to marry Princess Shu Yu. They suggest granting Madam He's foster daughter, Song Wu, the title of princess and marrying her to Mo Plains. Song Wu is happy, thinking it is a good thing to be granted a title. She feels despair when she finds out it is an attempt to marry her. (Source: Viu)
