6 months later
The Gupta family is now a happy family, and the three younger Gupta brothers see Shiv and Ganga as their parents. During a festive moment, Shiv and Ganga notice Alok and a character named Jaya's closeness and doubt the nature of their relationship. Once asked, Jaya reveals that she has been in love with Alok since childhood and believes that Alok, a changed man now, reciprocates her feelings. This leads Shiv and Ganga to mistakenly believe that Alok and Jaya love each other and, though he is initially reluctant, Shiv decides to marry off Alok and Jaya for his brother's happiness. It is then revealed that Alok loves another girl, Aditi, the daughter of one of their rich dealers Bansal. Upon learning more about Bansal, Alok broken-heartedly decides to marry Jaya. He breaks up with Aditi, making the untrue claim that his love for her was fake. On the day of Alok and Jaya's marriage, Aditi learns that Jaya's father intentionally ended hers and Alok's relationship, so she decides to win him back. She elopes from her house and emotionally blackmails Alok by threatening to commit suicide if he doesn't marry her. Helpless, Alok marries Aditi, shattering Jaya and her family. To secure Jaya's future, Ganga asks Veeru to marry Jaya, which both of them oppose, as they have always hated each other. However, in the end, for the sake of the happiness of their families, Veeru and Jaya agree to marry each other. Thus, Alok marries Aditi, while Veeru marries Jaya.
After Alok and Veeru's marriages, Ganga and Shiv struggle to keep their family united as constant issues crop up between Aditi and Jaya because Aditi is always insecure about Jaya's presence. Aditi also has difficulty adjusting to a middle-class lifestyle, as she has always led a luxurious life. Veeru and Jaya often argue with each other. Ganga and Shiv work hard to keep the unity of the family, but Amba still strives to divide them.
Thus, Amba instigates Bansal, who wants his daughter and son-in-law to live with him. Amba herself was using Bansal, as she wants her daughter, Jaya, to live a queen's life in the Gupta family. Provoked by Amba, Bansal stops all his supplies to the Gupta & Sons grocery store. This causes a major loss for the Guptas, so Shiv decides to get help from acquaintances of Mirzapur. In Shiv's Absence, a man named Mishra, who is helping Amba, offers help to the Gupta family. Alok decclines to accept the offer. However, Veeru, to help his family and to prove himself to Jaya, who considers him to be good-for-nothing, accepts Mishra's offer.
Amba's plan succeeds–the Health Inspectors inspect the stale and expired products in Gupta & Sons grocery store and end up sealing it. The Guptas are devastated, and things go downhill when the police arrest Alok for the Foodborne illness caused by Gupta & Sons' expired products. Shiv and Veeru try to save Alok by getting arrested instead of him, but Alok stops his brothers and gets arrested, taking full responsibility for the Foodborne illness. While Shiv and Veeru try to get Alok released, Ganga reaches out to Bansal for help. Bansal says that he will help Ganga if she allows Aditi and Alok to live with him. Ganga, angry that Bansal considers familial relationships as business, declines. As Ganga leaves, Bansal realizes that Aditi had overheard the entire conversation. Bansal tries to emotionally blackmail her, but Aditi confronts him for all his evil acts against her (Gupta) family and vows that she will break all ties with her father if he ever tries to plot against them.
Later, Ganga, Shiv and Veeru make up with the Foodborne illness victims' families and help Alok get released from jail. At the same time, Jaya catches Mishra, proving the Guptas' innocence. The whole Gupta family rejoice at overcoming the great trouble in their family. However, things are still unstable between Aditi and Jaya, with Jaya misunderstanding the main culprit behind all the scams in Gupta family to be Bansal instead of Amba. At the same time, Aditi insecure due to Alok and Jaya's proximity. However, Aditi, aware of her father's misdeeds, accepts the Gupta, forming a cordial relationship with everyone except for Jaya. Tensions are also present between Veeru and Jaya.
Ganga and Shiv send the newly-weds on their honeymoon. During their honeymoon, Veeru and Jaya had a huge brawl in the hotel, causing Jaya to leave the room saddened and annoyed. She is about to endanger herself when Alok saves her and promises Jaya that he will be always at her side as a friend. Aditi eavesdrops on their conversation. She then calls Veeru and questions his wife's character, to which Veeru's stays dumb. In the hotel room, Veeru assures Aditi that he trusts Jaya, having known of her friendship with Alok since childhood. This improves the relationship between Veeru and Jaya somewhat. Meanwhile, Aditi confesses to Alok how much insecure she is about his and Jaya's relationship, saying that she wants Alok to prove his loyalty to her.
In Banaras, Ganga and Shiv are called for a baby shower ceremony, where Ganga is criticized for being childless.

Jaya takes out her frustration on Veeru, saying her life is destroyed by marrying him. Veeru is heartbroken by Jaya's words and decides to divorce her for her betterment. At the same time, Amba tries to kill Aditi's unborn child, by poisoning her food. Jaya learns about her mother's plan and saves Aditi, breaking all ties with her mother. After this, Alok and Veeru decides to divorce their wives. To save their family and keep them united, Shiv and Ganga pretend that they've decided to separate. Aditi, Alok, Jaya, and Veeru decide to stop Shiv and Ganga from separating, causing them to realise their mistakes. Veeru and Jaya confess their feelings, and Jaya and Aditi mend their relationship.
