Xu Man is the daughter of the savior of the old man of the Ji family. In the words of the old man, there would be no Xu Man without his grandfather. So after Xu Man's grandfather passed away, he took Xu Man into the Ji family, so that her only granddaughter could marry Xu Man. "Sister, let's get a divorce." "Okay, find the marriage certificate first."
PS: People with gay backgrounds can get married.
Intention: Marriage first, love later.
