In order to inherit his core legacy, Lu Tingshen, an upstart in science and technology, needs a "perfect wife"; in order to get rid of the pressure of getting married and strive for a career change, designer Su Nian needs a marriage certificate. The two signed a contract and agreed to go their separate ways after one year. The cohabitation life began with the rules of the Chu-He-Han world, but it quietly deteriorated during family banquets when they joined forces to defeat the enemy, the fragility revealed after drunkenness, and the subconscious protection in times of crisis. When the contract was made public by the enemy, with the whole city in turmoil and his career on the verge of collapse, Lu Tingshen tore up the agreement in public: "The only thing I want to renew is the rest of our lives." From the cold parties of Party A and Party B to partners fighting side by side, they finally understood that the best contract is one written sincerely for the rest of their lives.
