Madam Ding was worried that she would not be able to get anything out of Du Bing, so she got a private investigator to look into this.
In the end, the investigation led to an accident. Only then did Madam Ding find out that not only was Mr. Ding having an affair, but he also had a child. The affair was actually with Du Bing!
Madam Ding was a person who could not hide anything. The moment she found out the truth, she caused a great scene with Mr. Ding, causing everyone around her to know about this scandal.
Mr. Ding had originally felt a little guilty toward Madam Ding, but after this commotion, he became a laughing stock. After slapping Madam Ding in front of everyone, he left the Ding family's villa.
From then on, Mr. Ding did not go home much. He and Du Bing bought a villa elsewhere to live together and raised their son personally.
