Gu Qingqing studied abroad for five years. When she returned from her studies, she was engaged to her middle school boyfriend Fang Zhengnan. On the eve of the engagement, she was taken to a strange and dilapidated house. After finally arriving at the engagement ceremony, she found that her boyfriend of more than ten years was standing next to a woman who looked exactly like her, holding her boyfriend's arm intimately.
