But when she grew older and lost her youthful beauty, Gu Jianguo joined forces with his mistress, Bai Zhiwei, to throw her out of the house. Their daughter, Gu Mengyan, witnessed her mother being humiliated in the pouring rain. Determined to reclaim the Su family fortune left by her maternal grandfather, she resolutely chose to 'accept her enemy as her mother,' enduring humiliation and hardship as she stayed with the Gu family. In the end, she takes down the entire Gu family.
