Lanzhou City is divided into Dongzhou and Xizhou. Due to a feud over resources a hundred years ago, they do not marry or do business with each other. Fu Sinian, the president of the Dongzhou Fu family (paranoid and ruthless, forbearing to investigate the truth about his mother's murder) and Su Wanqing, the daughter of the Su family in Xizhou (a brutal and sober person who protects the family and his grandfather), had a feud due to a feud at the Lanzhou Chamber of Commerce dinner. Later, because the Su family was jointly suppressed by Su Manyun and Fu Jingming, and Su Zhenhai became seriously ill, Fu Sinian helped the Su family out of the siege on the condition of a "contractual marriage", but in fact he wanted to use the heroine to investigate clues about his mother's relics. After the marriage, the two began to test each other, protect each other secretly, and gradually developed a secret love. However, they turned against each other because of Fu Jingming's forged evidence that "Fu Sinian killed the heroine's father." The heroine escalated her revenge and the hero struggled to protect her. Then Wen Zhiyu (the mysterious neutral) gradually intervened, combined with the evidence secretly collected by Su Zhenhai, to expose all the conspiracy. Fu Sinian opened the crematorium to pursue his wife, and made up for the misunderstanding with painful sacrifices. The male and female protagonists joined forces to dismantle Yege, Lanzhou Chamber of Commerce and other villains, thwarted Fu Jingming and Su Manyun's plan to seize power, and finally resolved the feud between the two continents, achieved two-way redemption, and harvested perfect love.
