"Enough, Sixth Son, what do you mean by saying these things now? Do you want me to quarrel with your brother-in-law, or have your brother-in-law go quarrel with my parents? Do you really want to see the third branch fall apart? Let me tell you, I won't let such a thing happen." Yu Si Niang scolded Yu Liulang loudly.
In Yu Si Niang's heart, what's past is past.
Since she married into the Old Mu Family, married Mu Dashan, she has the responsibility to keep this family united, to ensure everyone has a common goal. She's not the kind to make trouble without reason; everything from before was wiped clean after the family split.
From now on, as her daughter said, the third branch living well is truly living well.
Everything else has nothing to do with them.
Yu Liulang realized his words hurt his sister, and promptly spoke up to apologize.
