Liang Yan didn't want a divorce, so she sought out her superiors and caused a scene at the hospital.
She hoped the company's leaders could have a talk with Zhang Dong, urging him not to get divorced.
She hoped Granny Zhang would persuade Zhang Dong, after all, they're grandparents now, divorcing would just be a laughingstock.
The leaders at work did try to persuade Zhang Dong, but once he explained, they could only turn around and advise Liang Yan to let go.
As for Elder Mrs. Zhang, she was even more straightforward, directly notifying hospital security to throw her out, and warned if she caused more trouble, she'd call the police, thoroughly intimidating Liang Yan.
With no other options, she approached Zhang Hao, spoke with him and his wife about Zhang Dong wanting a divorce.
Zhang Hao was stunned, his first reaction was, of course, to find Zhang Dong.
