Anger can't solve anything; it only makes everything worse.
Her situation is not favorable right now.
If Zhou Sinian had her in his heart, she could reason out a confrontation with him. But under these circumstances, if she did so, she would only be despised by everyone, and it would leave a worse impression in Zhou Sinian's heart.
So she couldn't, and mustn't.
If she loses face again after doing it once, even she would despise herself.
It would also taint her reputation if she ever marries into the Zhou Family.
The Zhou Family would certainly not accept a young mistress with a tarnished reputation.
So she needs to calm down and plan for the future.
She first throws a gracious smile at the two women next to her: "Thank you, both of you earlier."
Regardless if they acted out of pretense or ulterior motives, they had supported her, saving her from disgrace by falling flat on the ground. She takes this favor to heart.
