Su Qi only introduced Liu Qing and did not say that he was the son of Ding Yun and her ex-husband. She was mainly afraid of trouble.
This kind of marriage was indeed a very strange thing. If he said it out loud, it would make the Su family unhappy, so there was no need for it.
They would definitely find out in the future. He just needed to let them digest it slowly. There was no need to say it in person.
Su Lao Er and his wife were not very happy about Liu Qing's appearance, but they also knew that they could not afford to offend such a person. They did not show that kind of displeasure and tried their best to control their emotions and express their enthusiasm.
They wanted more wealth, but that didn't mean they had lost their minds.
It was just a scene in a melodramatic drama to say something sarcastic and hateful because she was unhappy.
