Jiajia was the only child of the Zhai family. However, she was a female. If he performed well, he might be able to place Wei Wei by the Zhai family's side. As time passed by, Zhai Sheng might really be willing to nurture Wei Wei and give him a way out.
One should always dream. What if it became real?
If Wei Wei became the chief, even if he was just a regiment commander, he was still a chief's father. He would still reach the same goal albeit by different means.
However, Zhai Sheng was going to get married now. His match was Qiao Nan, a woman whom he couldn't even fancy. Wei De was very dissatisfied. On what basis did Zhai Sheng refuse to give him, the brother-in-law, face because of Qiao Nan? Back then, he didn't allow Zhai Hua to marry him. Until today, he had never officially addressed him as 'brother-in-law' once.
