Back to present.
Matriarch Li and Li Qinfeng couldn't come to a solution. The old woman was adamant to keep Lu Mimi as her daughter-in-law because she had long favored the younger woman.
Besides, Lu Mimi was smart and she knew how to listen. She also liked to sweettalk the old woman which made her like Lu Mimi's flattering and dependent attitude.
Matriarch Li wasn't interested in Li Qinfeng's woman and her bearings in life. She had long held a preconceived label that this outside woman was an uncultured and vile person who wouldn't listen to her as soon as she came into the door.
Li Qinfeng had no choice but to threaten his mother with his son. He told her that he wouldn't let his son live in the Li manor if she didn't allow his mother to come along. They couldn't be separated.
