Trust is a strange thing.
She did not want to explain the situation to Qin Zhiyou because she felt that there should be trust between husband and wife. She also did not want to ask Qin Zhiyou why he had met with Fang Rushuang without telling her, perhaps it was just for business cooperation, or maybe it was a casual encounter. Everyone has their privacy, she did, and so would Qin Zhiyou.
But she also knew that it was impossible for her heart not to flutter upon seeing him with Fang Rushuang. If she truly did not mind at all, it could only mean she had no place for Qin Zhiyou in her heart.
She was waiting for Qin Zhiyou to explain things to her. At least, in her previous collaboration with Qin Zhigu, she had reported it to Qin Zhiyou. This time, her discussion with Qin Zhigu in the hall about work matters was completely normal. If even this kind of contact was not allowed, then they should not continue living together.
