Su Nian, an ordinary urban white-collar worker, rescued an old man who had fainted on the street. Little did he know that the old man was the grandfather of Gu Jingchen, a business tycoon in Haicheng. At that time, the Gu Group was in deep crisis and was in urgent need of capital injection, but the partners actually asked Gu Jingchen to marry Su Nian. In desperation, Gu Jingchen proposed a one-year contract marriage to Su Nian.
The wedding was hasty. After the marriage, Gu Jingchen was busy with his career, while Su Nian stayed alone in the empty room. Their relationship was as cold as frost. However, a drunken confession by Gu Jingchen made Su Nian see the fatigue and fragility in his heart, and she began to try to enter his world.
Just when the relationship was warming up, Gu Jingchen's first love Lin Yue returned to China and deliberately sabotaged their marriage. Su Nian was full of misunderstandings and suffered endlessly. Occasionally, Su Nian discovered Lin Yue's conspiracy and revealed the truth to Gu Jingchen. The misunderstanding between the two was resolved, and their relationship quickly heated up.
Before the sweetness was over, the company was in crisis again. Gu Jingchen was busy day and night, but Su Nian never gave up and relied on his connections to help. In the end, can they work together to overcome the crisis and make this contract marriage a success?
