In order for her sister to calm down and sleep after having a late dinner, Tang Moyu had agreed to her sister's request to keep her whereabouts a secret. Not like their own mother would suspect that she was giving shelter and extending a hand to her Wan Jie right now, considering how bad their fight was the last time they saw each other.
Tang Moyu didn't want to see nor talk to her mother right now. There were so many questions she wanted to ask, but she knew it was pointless to confront their mother about why she was treating her daughters like this.
If anything else, Tang Beixuan was the only pampered child of all of them. While it was understandable that their father, Tang Lixue, and their mother, Zhang Wuying had adopted her elder sister three years before Tang Moyu was born, the empress thought that it wasn't a reason for the Tang family to treat her sister like this.
