Su Mo Mo and Sheng Tianyu, childhood sweethearts who grew up under the same roof, began to fall in love when they were in college. They have been in love for more than three years. Because Sheng Tianyu's parents looked down on Su Mo Mo and tried every means to force them to separate. The obstruction of the Sheng family's parents also made Su Mo Mo become less and less confident, thinking that he was not worthy of Sheng Tianyu. After an accident, Sheng Tianyu's parents created the illusion that Su Mo Mo had died unexpectedly. Su Momo, who was not confident, also took this opportunity to quietly withdraw from Sheng Tianyu's world. Sheng Tianyu was heartbroken. One day five years later, he met Su Momo who unexpectedly 'passed away' on the street. Under his forceful coercion, Su Momo could only go with him to get a marriage certificate. After getting married, Su Momo was still not recognized by the elders of the Sheng family. There was also a love rival who made things difficult for her. In order to get her to leave Sheng Tianyu, he used various means to make things difficult for her. Even though the elders of the Sheng family were not optimistic about Su Momo marrying into the Sheng family, Sheng Tianyu never thought of giving up on Su Momo. The appearance of Su Mo Mo's secret admirer made Sheng Tianyu realize the sense of crisis. Sheng Tianyu never backed down due to the embarrassment of his parents and the difficulties of his love rival. Instead, he defended Su Mo Mo at all times. Su Mo Mo saw every move of Sheng Tianyu, which made the originally unconfident Su Mo Mo more and more determined to stay with Sheng Tianyu. Their obstruction deepened the relationship between Sheng Tianyu and Su Momo. In the end, the two overcame many difficulties, came together sweetly and happily, and lived a happy life.
