After the eldest grandson Yu'er died in an accident, she was bound to the book-traveling system. In order to reverse the BE ending of the original book where her whole family died tragically and to clear her identity as the vicious female supporting role, she transformed into the domineering and domineering eldest daughter of the Su family, Su Qingyuan. Knowing that the original protagonist would end up as cannon fodder for bullying the male protagonist Lu Shiyan, she immediately switched to the "old mother" mode and worked conscientiously to take care of the dependent Lu Shiyan, just to survive by holding on to the male protagonist's lap. But she didn't notice that the male protagonist, who was once wary of her, was looking at her with passion.
