Pakistani television and novels frequently utilize specific tropes to explore the depth of a wife's relationship with her husband.
In any relationship, communication is key to building trust, intimacy, and understanding. In the context of Pakistani culture, the term "biwi" refers to a wife, and "adla badli" translates to "exchange" or "swap."
