Lawyer Zou Yu (played by Zhang Xinyi) met Lin Qizheng (played by Li Guangjie) because of a lawsuit, and then fell into a swamp of love. The gap in family background temporarily blinded the men and women in love, but the bad thing was that Zou Yu's sister Zou Yue (played by He Hongshan) was also infatuated with the suave Lin. Lin's fiancée Jiang Xinyao (played by Yang Shuting) is the sister of Jiang Xinhai (played by Shi Zhaoqi), chairman of Jiang Group. She has a strong possessiveness. She believes that Lin Qizheng can only belong to her and not others, and her love for Lin Qizheng is extremely selfish and cannot be touched by others.

Zou Yu was exhausted physically and mentally. She re-examined herself as if she had met her sister for the first time...
