Su Qingyuan once regarded Gu Yanchen as her salvation, but on the eve of their engagement, she discovered that her parents' car accident was his conspiracy to seize the family property. She turned around and got married to the mysterious boss Shen Muyao. She thought it was just a contractual relationship where each got what they wanted, but she gradually developed feelings for him through repeated confrontations and protections. When Gu Yanchen made a mad counterattack, Shen Muyao's words "This is your sister-in-law" not only declared his sovereignty, but also closely linked the fate of the two. From mutual temptation on the road of revenge to the dependence on life and death in fighting side by side, she rebuilt the kingdom on the ruins and found the warmth of love under the cold contract.
