For seventeen years, Cheng Yan has been searching for his lost love Sang Sang, never realizing that his new bride Gu Qingning is actually the very person he has been looking for. However, the Cheng family's housekeeper He Qingqing has always harbored the delusion of becoming Cheng Yan's wife, so she falsely claims to be Sang Sang and subjects Gu Qingning to every kind of abuse.
