The female scholar greatly dislikes people who are furtive and evasive, finding them too petty and thus offensive.
As the saying goes, once a teacher, always a father, yet Qu Fulan does not even reveal her master's real name. This shows she lacks respect for her teacher and the teachings.
Although the female scholar does not concern herself with worldly matters, she has heard quite a bit about the happenings in Pei Mansion, especially regarding Qu Fulan, who quickly became the lady attending the Princely Heir.
It seems she pretended she couldn't play chess to amaze the Heir.
However, the female scholar disdainfully refrains from exposing her. Though she is no longer a noble young lady, her upbringing is engrained in her.
There is no need to lower her status for someone so insignificant.
Originally, she thought Qu Fulan was unique enough to be favored by Mrs. Pei and the Heir. Now it seems she is quite ordinary.
