Su Qingyu and Shen Z

"Sister, don't waste your effort. You'll never leave this house for the rest of your life. Our husbands have brought a doctor.","Besides being the legitimate daughter of a marquis's household, what do you have that surpasses me If not for my family background, how could I possibly lose to you","Ever since Master Shen left, the first and second branches have started to vie for power. It's thanks to my full support that you've gotten this far; I even used my dowry money to help you out, and I went to ask your uncle and cousin for help with business matters."。
