In other words, Mu Huan didn't want to marry him back then. It wasn't the case that she got to know about her son's plan to marry through Chenyi, nor was she just using him to seduce her son.
She didn't even know that she was marrying her ex-boyfriend's uncle. Thus, she couldn't be in the wrong.
Moreover, the two of them were just like what her son had said. They could not be considered dating because they had never even held hands.
Furthermore, she knew that her son liked this daughter-in-law a lot at the start, let alone now. He was a cold-hearted son who had never done anything like that since he was young. Hence, she could not bear to give her daughter-in-law the same treatment as her father did.
Also, she heard from her sister that this daughter-in-law had saved Yuqi twice. This meant that her daughter-in-law was a good person. At the very least, there was a guarantee that she was kind.
