No, it's impossible, Chengzhou couldn't possibly have told her such private matters.
Mu Yiyao quickly calmed herself, "Chengzhou did indeed propose to me, but you're married to him now, why cling to the past? As I said before, we're just friends now. Are you insisting I cut off ties with him before you're satisfied?"
"Sang Qian, who do you think you are?" Shen Zhiqiu said disdainfully, "The years of affection between Brother Ji and Yiyao aren't something you can just cut off on a whim. Do you really think your seductive wiles can make Brother Ji obey your every whim?"
Sang Qian didn't respond to Shen Zhiqiu, instead, she looked at Mu Yiyao, who was always stirring things up in secret, "Miss Mu, when have I clung to the past? And when did I say you have to cut ties with Ji Chengzhou? Your tactics of quietly slandering people are really clever."
