This work shows the importance of emotions in work, love, and life by showing the story of a young man and woman who fall in love while pursuing their dreams. The data analysis that the male protagonist Cheng Xu firmly believes in is an intention, representing rigorous and objective absolute rationality. The cake that the female protagonist Mu Si loves is an intention, representing sensibility. The love that the two have is also an intention, representing the whole emotional life. Although objective data is absolutely solid and reliable, data analysis is not all of life. Humans are creatures with emotions after all, and emotional fullness is a necessary condition for a happy life. Whether it is a firm belief in self-value judgment, a persistent pursuit of dreams, or a mutually attractive and supportive relationship, it is a way of expressing emotions. The construction of a complete and beautiful relationship is to not lose humanity on the basis of rationality, and not lose reason on the basis of sensibility. Only the harmonious coexistence of the two can bring a better life.
