An Nuan and her husband Feng Kai have been married for three years. After marriage, under the pretext that his mother Zhang Guilan was in poor health and needed surgery, Feng Kai made An Nuan spend both money and effort, and even moved Zhang Guilan into An Nuan's pre-marital house to live. An Nuan had always treated Feng Kai's family as her true family, not only bearing a large amount of expenses for the household, but never grudging Zhang Guilan's food, clothing, health care, and medical treatment. However, her dedication did not win respect in return, but instead made Zhang Guilan more and more taken for granted, and instead made Zhang Guilan more and more taken for granted, to bear everything for herself.
