To put it bluntly, Liu Mingchen's father hoped that Lin Nuan wouldn't help Liu Mingchen garner the attention that he wanted. He wanted the issue to remain silent, like putting a piece of paper into water.
Liu Mingchen's father's feelings were just like Lin Nuan's, who would put Fu Huai'an at the top of her considerations in things, not wanting him to be in a position of danger, and not wanting him to be overly tired.
There were too many injustices in the world, and one would merely be alive for several decades, perhaps a hundred years. One couldn't possibly have enough energy to make their family reassured and blissful while fighting for all of the injustices in the world at the same time!
After a momentary silence, Lin Nuan nodded. "I understand!"
Liu Mingchen's father nodded. "I knew you were a bright child! I also know that you're a child who's considerate of her family, so you definitely understand my feelings as a father!"
