Lilith and Lucas, president of the Rockefeller Group, signed a one-year "contractual relationship" contract, during which they gradually developed genuine feelings for each other. As the contract expired, Lucas's ex-girlfriend, Victoria, returned to the country in a high-profile manner, attempting to regain her position by faking an illness and a marriage of convenience. Through Lilith's clever maneuvering and Lucas's unwavering commitment, Victoria's schemes were exposed one after another. Ultimately, witnessed and tested by his family elders, Lucas realized his true feelings, not only resolving his entanglement with Victoria's family but also officially acknowledging Lilith as his partner at the end of the contract.
