Su Miaoyan thought briefly, it wasn't about money that Mu Family's Master refused to let Mu Qianya marry Brother Yu, then it must be about status.
She pondered for a moment, and softly said, "If Mu Family's Master worries about the status of Sister Mu after she marries into our family, rest assured. Though I come from the Marquis's Manor, I am not incapable of accommodating others. Sister Mu is easy to get along with, and I don't mind sharing my husband with her as a secondary consort, as long as she supports my husband well. Naturally, she will have more dignity than the other concubines."
Parents probably care about the status within the family and the household.
