In literature, the word "contract" is employed in a variety of ways to reflect its complex nature both as a literal legal instrument and as a metaphor for mutual obligations or binding social agreements. Legal thinkers and jurists describe it in context of formal conditions and stipulations that define duties between parties [1, 2, 3], while political philosophers extend the concept to the foundation of society, as seen in discussions of the social contract [4, 5, 6]. Dramatic writers, such as Shakespeare, adapt the term to capture themes of commitment and the binding nature of relationships, whether in marriage or in the more abstract sense of love’s obligations [7, 8, 9]. Moreover, the term is sometimes metaphorically applied in narratives to signal a contraction of emotions or a broader life commitment [10, 11], demonstrating its versatility across genres and historical periods.
