Final answer:

Step-by-step explanation:
The theory of love as a love story was developed by Robert Sternberg. Sternberg's triangular theory of love proposes that love can be understood in terms of three components that together can be viewed as forming the vertices of a triangle. These components are intimacy, passion, and commitment. When these three components are combined in different ways, they form different types of love experiences. Sternberg articulated this theory in his work published in the Psychological Review in 1986.
