In order to save the family business, stand-in heroine Shen Yuan signed a three-year lover contract with the domineering president Gu Chenzhou. Because she looks like Gu Chenzhou's first love, Moonlight Su Wan, she became a talk in the industry. For three years, Shen Ying exercised restraint and acted as a perfect substitute, but in fact, she secretly accumulated strength and planned her future clearly. On the day when the contract expired, which coincided with Ziyueguang's high-profile return, Shen Yuan decided to leave in public. Gu Chenzhou was dismissive at first, believing that she would look back, but when he witnessed Shen Yuan truly moving towards a new life and getting engaged to someone else, he completely lost control and regretted it beyond measure.
