Her only worry was the powerful ally backing the protagonist.Then she discovered that the protagonist’s powerful ally was none other than the beautiful young man her father had rescued from the icy river last month!So Jiang Mianmian was completely reassured. With this life-saving favor, the young man would definitely not side with the protagonist against her family in the future.Moreover, Dashan took the initiative and said, “Little Lamb, I’d like to court you with the intent of getting a marriage license, is that okay?”As someone obsessed with good looks, Jiang Mianmian struggled and then reluctantly refused, “No, I plan to have a son-in-law who will marry into the family.”The powerful ally didn’t hesitate, “Then I’ll be the son-in-law who marries into the family, and the children will take the Jiang surname!”Jiang Mianmian: “Let’s go, get the marriage license!”
