When Ding Jiayi was muddleheaded and Qiao Nan was almost forced into a dead end, it was Qiao Dongliang who decided to file for divorce and draw the line with Ding Jiayi. It was only through a divorce could he stop Ding Jiayi from scheming against Qiao Nan.
If Qiao Dongliang did not file for a divorce—even if Qiao Nan would marry Zhai Sheng eventually—she would have to go through twice as much trouble and difficulties.
It was due to Qiao Zijin that Ding Jiayi treated Qiao Nan badly.
Therefore, in the entire Qiao family, Qiao Nan would only turn soft-hearted on Qiao Dongliang.
Qiao Zijin could not offend Qiao Dongliang. Instead, she must please him such that he would treat her like how Ding Jiayi treated her and do his best to help her. She must not lose her father again.
If she lost his support, Qiao Nan would definitely rejoice over it.
