An accidental drowning and long-term brain hypoxia caused the famous fashion designer Li Weiwei to lose some of her memory. Her memory stayed at the age of 23. Her boyfriend, who was also a designer, became her competitor, and a stranger became her fiancé. Weiwei didn't believe that she would break up with her ex-boyfriend Chen Yidu, and she tried to investigate the cause. In order to protect Weiwei and get his fiancée back, her fiancé Huo Xiao did everything he could to obstruct Weiwei's investigation and stayed around her. Li Weiwei looked back on the past and found that she and the people around her gradually forgot their original dreams in the busyness. The reason why Weiwei and Chen Yidu broke up was that in the process of pursuing their careers, they ignored love and communication, and went further and further on the road of grudges and misunderstandings. Chen Yidu misunderstood the relationship between Weiwei and Huo Xiao and finally broke up with her. The 30-year-old Li Weiwei decided to change the status quo. She gradually solved the misunderstandings of the past and cleared up the past with her opponents. Not only did she find love again, but she also regained her original intention and dream.
