A wedding was a ceremonial ritual that involved not only the union between the groom and the bride but also the union between the two families of the two people. In this era, marriages took place at the behest of the parents and the word of the matchmaker, and that was why it was normal if the man and woman who were getting married did not know each other.
Nonetheless, there would always be a bride and groom at every wedding even if the groom and bride didn't know each other, and yesterday when Yu Ming mentioned the word "your wedding" in front of Wu Jingguo, he indirectly referred that Wu Jingguo would be the groom in the ritual.
