In fact, Qin Zhiyou and Lu Weixi had not expected to face their parents so soon.
When Lu Weixi opened the door for him, he was standing outside, entering shoulder to shoulder with her.
Lu Weixi had just pushed him out, but he hadn't left. With such a commotion, Mom Lu could not have missed it.
He worried Mom Lu would get angry at Lu Weixi. After all, she was the one who had instigated their divorce and could hard-heartedly ignore her daughter for months. Now, as Lu Weixi was pregnant, if Mom Lu got angry and shoved her, causing harm to her belly, that would be terrible.
Moreover, Mom Lu had chronic health issues herself. If she got so angry that it caused her harm, Lu Weixi, with a child late at night, would have trouble taking care of everything. At least if he was there, he could help out.
