Ego

By the end of the day, everything was solved between the families other than Zeng Ruo's resentment towards Feng Dingxiong. However, looking at her daughter's happiness, she didn't have the heart to separate her from Feng Jianyu. If she did, what would be the difference between her and her father?

Moreover, she agreed on the point where Feng Dingxiong asked not to punish his son for his wrongdoings. Feng Jianyu had saved Xiu Mei's life years back; her resentment towards him diluted a little seeing him sincere towards her daughter. And above that, looking at her repo with the Feng family, it highly likely that one wrong step will push her away from Xiu Mei forever.

Mo Zhichan knew his wife was still sour towards Feng Dingxiong but he didn't force her to do anything that she didn't want to.  Few things cannot be solved overnight....

It's an old wound… and will definitely take time to heal. Maybe with time, everything might return to as it was before.
