Su Rao and Gu Nanting have been married for three years, but their marriage has always been in an "underground state" - Gu Nanting has never disclosed his wife's identity, and has a close relationship with Bai Yueguang Cheng Lu (Su Rao's half-sister). Su Rao suffered a lot of injustice, and finally divorced Gu Nanting, and turned to the second male lead Gu Mingchen (Gu Nanting's uncle) who had been silently protecting her.
