Zhou Jingyun must still be thinking about splitting the inheritance, seeing as she and Bai Zhenhong are legally wed. However, she believes that her scumbag father wouldn't let Zhou Jingyun have her way. It's very likely that scumbag dad had registered a prenuptial agreement, it's just that Zhou Jingyun doesn't know about it.
As long as Bai Zhenhong gets called into the police station, then Zhou Jingyun won't be able to escape either. Given Bai Zhenhong's current resentful mindset toward her, he will definitely drag Zhou Jingyun into this.
It's just that the Bai siblings haven't been able to be punished together yet. Although Bai Tong has bullied her, it's just bullying at most, and the law can't do anything to Bai Tong yet.
