The two people who originally had nothing to do with each other begin a marriage that starts with a contractual agreement after an embarrassing mix-up. Facing family pressure and a business crisis, Pei Yanchen proposes a marriage of convenience based on mutual cooperation. She becomes his wife, while he helps her protect her family's business. Shen Qingming initially believes this is merely a transaction in which both parties get what they need. However, through their daily life together after marriage, she gradually discovers that beneath this cold and stern man's exterior lies an unexpected tenderness and a desire to protect her.
