The Su family went bankrupt overnight, and the former proud daughter became the laughing stock of others. Just when the Lu family was hastily choosing a marriage to save the company and planning to marry randomly in exchange for resources, Su Xiaoxiao, who had disappeared for half a year, parachuted into the engagement scene with tens of millions of capital. With a one-year engagement, she paid to help Lu Yanci stabilize the Lu family, which was on the verge of collapse, and he became her contractual husband to support the public. Everyone laughed at Su Xiaoxiao for overestimating his abilities and spending all his savings to support a wealthy and down-to-earth CEO. Little did they know that Su Xiaoxiao was working hard at every step, quietly cannibalizing the group's inferior industries. As they get along with each other for a long time, the cold and ascetic Mr. Lu gradually falls into decline, from "coping with the contract" to trying every means to renew the contract. The bankruptcy conspiracy that had been buried for many years came to light, and the former enemies joined forces for revenge. When the dust settled, Lu Yanci placed the entire group's shares in front of her: "The engagement is void, and the marriage certificate will be valid for the rest of my life."
