One day, she had a dream, and the setting was in a novel. In the novel, for the sake of alleviating his pain of losing his wife, and soon his daughter as well, her father adopted a girl named Chen Xiangxiang who looked just like her. The girl was docile as a deer and very therapeutic, which made her all the more lovable. This girl became her substitute, and after a series of heart-wrenching incidents, everyone, from her father, brother, fiance, to her friends, they all doted on this girl.
