When the earthquake struck, Huo Lan and her daughter Shen Xue'er were buried under a slab of stone. Huo Lan's father, Huo Zhengting, faced a dilemma of choosing between the two. Huo Lan urged her father to save her daughter Shen Xue'er, while she herself was rescued by the orphan Gu Ruoruo. Eighteen years later, the amnesiac Huo Lan, now renamed Gu Shuang, worked as a laborer in the Shen Group. Her adopted daughter Gu Ruoruo went to the Shen Group for an interview. Receptionist Yang Na deliberately picked on Gu Shuang, humiliating her in public. Manager Li Qi, who happened to pass by, sided with Yang Na and reprimanded Gu Shuang. At that moment, Gu Ruoruo emerged from her interview and, seeing Gu Shuang being bullied, stood up for her, thus beginning a tale of entangled grudges and grievances.
