"The Zhai family isn't aware of this matter. If they did, Zhai Hua wouldn't have married your father. Until now, the Zhai family still doesn't know about this."
Although Wei Xiaomei didn't want to say it, the meaning she expressed was very clear. Compared to her, the Zhai family was considered a victim too. The Zhai family didn't have to use power to snatch Wei De away as a son-in-law. Wei De wasn't that outstanding, and the Zhai family wasn't willing to do such immoral things.
Everything was based on Wei De's deception to the Zhai family. If the Zhai family knew that Wei De had a wife and a child, they would naturally ask him to get lost as far as possible.
