Shen Man, a new mother post-childbirth, thought she would have to swallow the grievances in her marriage alone. Little did she know that the princess mother-in-law, pampered all her life and full of antics, would become her strongest backing. Unable to stand anyone bullying her daughter-in-law under her nose, the mother-in-law stood firmly by Shen Man's side time and again, backing her up and clearing her doubts. When her husband failed to learn boundaries and took politeness as a blessing, Shen Man did not sink, but instead turned away bravely, starting a new life with her daughter. The mother-in-law stuffed real estate, confidence, and all her favoritism into her hands: no one in the Cheng family can be wronged.
