Arun left home after a heated quarrel with his father, who strongly disapproved of his singing career and considered it unsuitable for their family's status. To pursue his passion while avoiding his father's interference, Arun moved to Calcutta and created a new identity as Sanjay Kumar, allowing him to sing at the local radio station without his family knowing.

The conflict between Arun and his father over his future is established early, showing that Arun's departure was inevitable once his father refused to accept his dreams.

Mathur discovered Arun's true identity when he learned that Arun was the escaped son of his longtime friend Chaudhury. This revelation came to Mathur directly, and he then informed Arun about the connection between their families.

Arun decided to organize the stage show after Shrikant's health deteriorated to end-stage tuberculosis. When Arun saw his ill friend and learned that Shrikant needed an operation he couldn't afford, he was driven by loyalty and compassion to help. The stage show was his way of using his singing talent to raise the money needed for the life-saving procedure.

Earlier in the story, Arun is shown helping Shrikant financially, demonstrating the depth of their friendship and setting up his willingness to go to extreme lengths for his friend.

The surgeon revealed that Shrikant's mother was actually Mathur's lost daughter-in-law, his son's wife who had disappeared during wartime. This discovery meant that Mathur had been unknowingly searching for his own grandson all along, linking Shrikant directly to Mathur's family through this tragic separation.

Mathur's persistent search for his daughter-in-law and grandson is established early in the timeline, creating the foundation for this later revelation.

Arun's father changed his perspective after witnessing his son's success in Calcutta and the impact of his music, he organized a life-saving stage show that saved his friend's life. Seeing Arun's talent, determination, and the positive outcomes of his career convinced the father that singing was a respectable path worthy of support.

The story indicates that the truth about Arun's identity was revealed, though the exact moment isn't detailed in the summary. Mathur's discovery that Arun was Chaudhury's son and his subsequent revelation to Arun suggests that the truth about Sanjay Kumar's identity also came to light, allowing Sunita to understand the man she had fallen in love with was the same person she admired as a singer.

Sunita's growing admiration for Sanjay Kumar as a singer while living in the same household as Arun creates the setup for this eventual revelation.

While in Calcutta under the name Sanjay Kumar, Arun worked two jobs, he was a singer at the local radio station pursuing his musical dreams, and he also worked as a driver for Mr. Mathur. This dual life allowed him to maintain his secret identity while earning a living and eventually building connections in the city.

Shrikant had been living in poverty, writing songs and articles to survive, which worsened his chronic illness. His condition eventually progressed to end-stage tuberculosis, requiring a costly operation that he couldn't afford. The combination of his poor living conditions and lack of medical care allowed the disease to advance to a life-threatening stage.

The story establishes early that Shrikant lived in a poor neighborhood and struggled with chronic illness, making his later deterioration believable.

Arun met Mathur and Sunita when he took a job as Mathur's driver in Calcutta. He lived in Mathur's household while working there, which is where he became close to Sunita. This living arrangement allowed Arun to pursue his singing career at the local radio station while maintaining his secret identity.

Arun's father believed that a career in singing wasn't fitting for someone of their wealthy family's status. He viewed performing artistically as unsuitable and pushed Arun toward the family business instead, creating the central conflict that drove Arun to leave home and pursue his passion in secret.
