Don't tell her that he was afraid of his father's dignity and cared about the family's face. To put it bluntly, he was a cowardly man who bullied the weak and feared the strong.
He clearly did not like Yan Ze's mother and was dissatisfied with the marriage that Old Master Yan had arranged for him. However, he was afraid that his father would cut off his source of income, so he could only reluctantly accept it.
If she really didn't like him, would she force him to do that? On one hand, she slept with him, and on the other hand, she despised him in front of outsiders.
What a scumbag!
In her opinion, such a man was the most selfish. He probably liked himself the most. For the sake of wealth, he would be willing to give up anything.
Thinking about it this way, that concubine might not have loved him deeply, but she had not touched his bottom line yet. Or perhaps that white lotus had extremely high means to coax that scumbag, so that scumbag was blind.
