They wanted her and Seventh Master to get along and bond later.
Seventh Master had told Mu Anan that he would not choose Tang Mi.
Mu Anan was also very polite to Tang Mi. Even if they had a conflict, it would be in secret and not on the surface.
On the one hand, it would be undignified.
Mu Anan did not want that after she sent Tang Mi away, Tang Mi would go to the Zong family and tell the Zong family that the reason why she failed in her match with Zong Zhengyu was that Zong Zhengyu had an unreasonable girl by his side.
Mu Anan tried to hold it in, but in the end, she couldn't.
"Young lady Tang, it's a matter between me and Seventh Master. After all, you're only here as a guest for fun, so keep in a good mood."
