As Rohan grows older, he becomes increasingly aware of his mother's sacrifices and the burden she carries on her shoulders. He promises himself that he will do everything in his power to make his mother's life easier and happier. When his mother falls ill, Rohan takes it upon himself to care for her, cooking, cleaning, and nursing her back to health.

As Rohan's mother recovers, Rohan works hard to fulfill his promise. He studies diligently, gets a good job, and starts earning a steady income. He takes care of his mother's needs, buys her favorite foods, and spends quality time with her.

In the rich literary tradition of Bengali literature, Bangla Choti Kahini (short stories) have always been a popular medium for storytelling. These concise yet impactful tales often explore themes of love, family, and relationships. One such heartwarming story is "A Son's Promise To His Mom," which beautifully captures the unconditional love and devotion of a son towards his mother.

One day, Rohan's mother, unable to work due to her illness, calls him to her bedside and asks him to promise her that he will take care of himself and make a better life for himself. Rohan, overwhelmed with emotion, promises his mother that he will do everything she asks of him and make her proud.
