Plot
The show opens with a family of four bachelor brothers, Shiv, Alok, Veeru and Rajat, living in Banaras. They are well-versed in many things, from doing household chores to managing a business in a local grocery store; as a result, the four brothers are called the Sarvagun Sampann Gupta Brothers in their neighborhood. The four brothers are self-reliant and feel a woman is unnecessary, deciding to remain unmarried. However, when a character named Ganga creates a fake identity and enters the lives of the Gupta Brothers, their worlds turn upside-down.
All four brothers try to get rid of her, while simultaneously trying to discover the truth. Shiv discovers that Ganga is an orphan and develops a soft spot for her, forgiving her despite her misdeeds against the brothers. Ganga is amazed by Shiv's kindness and instantly takes a liking for him, which soon develops into love. However, Shiv, unaware of Ganga's feelings, decides to get her married to another man, which Ganga accepts brokenheartedly. On the day of the wedding, the groom elopes; Shiv then marries Ganga to save her honor. Shiv and Ganga's marriage leaves Alok, Veeru and Rajat shattered, causing a rift to form between Shiv and the three. They decide never to accept Ganga as their brother's wife.
Later, it is revealed that Shiv and Ganga's marriage was an evil ploy created by a character named Amba. She continues to provoke Alok, Veeru and Rajat by revealing that they are Shiv's step-brothers, and constantly plotting against the brothers. Rajat, moved by Ganga's kindness, accepts her, but Alok and Veeru still refuse to accept her. Ganga uncovers Amba's plotting and vows to protect her family. She reveals everything to Shiv, risking her marriage. Shiv is shocked to learn what Amba has done, breaks all ties with her, and starts to reciprocate Ganga's feelings. Amba, dejected, decides to kill Ganga.
Unfortunately, Alok, Veeru and Rajat fall prey to her evil plan. Ganga puts her life at stake and saves all three of them; this moves both Alok and Veeru, and they realize that they had been wrong about her after all. Finally, Shiv's brothers accept Ganga and name her as their Bhabhi-maa.
7 days later
Alok, Veeru, and Rajat arrange Shiv and Ganga's nuptial night, where Ganga decides to delay starting a family until Shiv's brothers, who Ganga now considers as her own children, are completely settled. Shiv is taken aback, but respects and accepts Ganga's bold decision.
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 wonder about 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 brokenheartedly decides to marry Jaya. He breaks up with Aditi, lying and claiming 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 escapes 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 declines 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 and the Health Inspectors inspect the stale and expired products in Gupta & Sons grocery store and seal 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 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 believing the main culprit behind all the problems in the Gupta family to be Bansal instead of Amba. Aditi is insecure due to Alok and Jaya's proximity. However, Aditi, aware of her father's misdeeds, accepts the Guptas, 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 have 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. 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 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. Rajat retaliates by calling Ganga Bhabhi-maa and affirming that Ganga is also his mother. Later, Ganga and Shiv decide to renovate and enlarge their house for the comfort of the newly-weds. During the puja of house renovation, Aditi, Alok, Veeru, and Jaya surprise everyone with their return. The Gupta family is overjoyed when Aditi tells them she is pregnant, except for Jaya, who feels like she is being ignored by Aditi. Her dejection increases as Amba poisons her mind more. Jaya takes out her frustration on Veeru, saying her life is destroyed by marrying him. Veeru is heartbroken by Jaya's words and believes divorce will make her happy. 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. Shiv and Ganga reveal what their plan had been and all of them live happily ever after.
