After calling Quan Hou Chi, Bai Gu Wen called her brother, Bai Xia Fang to inform him that her daughter already agreed to the invitation. Yes, Bai Gu Wen contacted Quon Hou Chi under Bai Xia Fang's order. It was not like she wanted to contact her daughter.
Bai Gu Wen depended on Bai Xia Fang for her living expenses. That was why she harassed her daughter by contacting her daughter multiple times until her daughter agreed to her invitation. It was not like she wanted to dine with her daughter at all.
Bai Xia Fang was happy that her niece finally agreed to have dinner together. He gave some money to Bai Gu Wen as the award. Of course, Bai Gu Wen was happy with the reward that her brother gave to her.
In order not to make things awkward during the dinner, Bai Xia Fang decided to inform his father about the matter. He wanted them to join the dinner as well.
