Final answer:
The idea of marriage is often introduced by society and family in the examples provided, but within the relationship, Kismine is the one who mentions the desire for marriage first in a direct conversation.
Step-by-step explanation:
Regarding the question on who mentions the idea of marriage first, it's apparent that the notion is brought up through various social cues rather than by the individuals themselves. In the context given, friends, family, and societal expectations play a significant role in introducing the topic into the couple's life, sometimes as small talk at weddings, or through more direct pressures from family members such as Elena's grandmother and aunts discussing the norms from their home country. It's reflected that in different societies and times, the concept of marriage and how it is approached could vary significantly, as seen through the lens of customs from places like New York City or a traditional Kolkata family.
In the narratives provided, Kismine is the one who openly expresses the desire for marriage in a casual conversation. This contrasts the societal pressures depicted elsewhere and highlights a more personal and direct mention of marriage coming from within the relationship, even though it's embedded in the critique of wealth and societal expectations in America. Such a declaration illustrates how individuals might navigate their personal desires within the broader societal constructs surrounding the institution of marriage.
