Lu Chaoyang, the heir to the top jewelry group "Bright Star", looks like a bright and funny person but is actually very business-savvy. In order to get rid of the family marriage and appease his seriously ill grandma, he signed a one-year "contract marriage" agreement with his personal assistant Su Nian, who is very capable at work but socially awkward and arrogant in private. Su Nian originally wanted to focus on making money and taking care of things, but she gradually became addicted to Lu Chaoyang's blatant preference and funny and warm daily life. At the same time, various forces that are jealous of the company or the two people (such as partners who admire Lu Chaoyang, colleagues who are jealous of Su Nian, and family branches who try to control Lu Chaoyang's marriage) continue to cause trouble and misunderstandings. Su Nian relies on his professionalism and inadvertently cute sincerity, and with Lu Chaoyang's tacit cooperation, he resolves crises and slaps villains in the face with elegance and calmness time and time again. Under the framework of "fake drama", the two experienced various events in which they jointly faced business challenges, solved their knots, and protected each other. In the end, they "acted for real" and recognized that each other was the only true love. They spent the rest of their lives hand in hand, and achieved both career and love.
