In Shanghai in 1927, the eldest daughter of the Shen family, Shen Qingyi, returned from studying in Paris, only to find that her family had gone bankrupt due to a business conspiracy, her father died unjustly, and her mother was crazy. The driving force behind all this is Gu Linyuan, whom she had fallen in love with when she was young and is now an upstart in Shanghai's business community.
In order to take revenge, Shen Qingyi entered the Gu family incognito and became the tutor of Gu Linyuan's younger brother. She used gentleness as her blade and forbearance as her armor, and worked every step to destroy everything about Gu Linyuan. However, when she finally forced the Gu family into a desperate situation, she discovered another side of the truth - there was another hidden reason for her father's death, and Gu Linyuan's "owe" to her over the years was actually protection in the name of love.
When she wanted to stop, it was too late. Gu Linyuan still protected her despite the betrayal and separation, and finally blocked the fatal shot for her. Only when Shen Qingyi held him on the verge of death did she understand his deep affection hidden under his coldness. For the rest of her life, she guarded his property, guarded the words "I never hated you" that she had no time to say, and repaid this love in the name of hate alone in the dim lights of the ten-mile foreign market.
