Azreen shows responsibility to her family in several ways:
1. She postpones her studies in London to care for her sick mother, taking on household responsibilities like cooking, cleaning, and pushing her mother's wheelchair.
2. As the sister, she feels responsible for finding the truth about her other sister Madhuri's death to clear her name and stop rumors in the village.
3. Azreen studies hard and earns a scholarship to further her education in London to become independent and eventually support her family, as she sees education as a way to improve their lives.
