Su Momo and Sheng Tianyu grew up together under the same roof. They started dating in college and were together for more than three years. Sheng Tianyu's parents looked down on Su Momo and did everything they could to force them apart. Their constant interference made Su Momo increasingly insecure, until she believed she wasn't good enough for Sheng Tianyu. After an accident, his parents made it look as though Su Momo had died. Already lacking confidence, she took the opportunity to quietly disappear from Sheng Tianyu's life. He was heartbroken. Then, one day five years later, he unexpectedly ran into Su Momo on the street, the woman he thought had died. Under his forceful insistence, Su Momo had no choice but to go with him and register their marriage. Even after the wedding, Sheng Tianyu's elders still refused to accept her, and a romantic rival made trouble for her at every turn, using all kinds of underhanded tactics to drive her away from him. No matter how much his family disapproved of Su Momo joining the Sheng family, Sheng Tianyu never considered giving up on her. The appearance of someone who had a crush on Su Momo made Sheng Tianyu feel even more threatened. He never backed down in the face of his family's hostility or his rival's schemes, and always stood up for Su Momo. She saw every one of his actions, and her confidence gradually grew. She became more and more certain that she wanted to stay with Sheng Tianyu forever. All the obstacles only deepened their love. In the end, they overcame every difficulty and found happiness together, living a sweet and blissful life.
