The narrative exposes the complexities of love, culture, and identity in the context of British colonial rule and post-colonial India.

As she navigates her new life, she faces the challenges of isolation and the pressures of traditional roles, which ultimately lead to a dramatic transformation in her character and worldview. Her journey is a poignant examination of the immigrant experience, the clash of cultures, and the personal quest for self-realization amidst societal constraints.
