Aspiring singer, Vandana Karmarkar lives with her father Vijay, aunt, younger sister, Mrunal, older brother, Hemant, his wife Anagha and their son, Shivam. She has been in a relationship with Vaibhav for about five years and is now about to marry him. She wishes to be a playback artist and auditions for a job. Kunal Malhotra hates India and is forced to go back to find the next great artist in Mumbai. He hears Vandana's voice and hates it and tells her that she will never be able to become a playback singer. Disheartened, she challenges him and vows to become the best. Kunal's aunt, Pammi, wants to live with him along with her son, Bobby, a viral social media influencer who is kind-hearted, and her husband and they move in next door to Vandana's house. Vandana is assaulted by a future employer and runs out of the room crying. Kunal sees her crying as he has a meeting with the employer for him to invest in this music label. He asks the man why Vandana was crying and he says that Vandana forced herself onto him. Kunal, knowing that Vandana's most important quality is her dignity and self-respect, beats up the man and cancels the deal. He leaves and finds Vandana, who falls unconscious. He carries her to her house and at the house are Vaibhav and his family. Vaibhav gets mad at Kunal and Kunal reveals that he saw Vaibhav at a cafe with another woman, which goes unnoticed by everyone else.
Vandana and her family get invited to a party hosted by the Malhotras while Kunal's father, Kuldeep, doesn't like the Karmarkars. He and Pammi decide to get rid of Vandana and her family. Pammi insults Vandana's aunt and Vandana grabs Kuldeep by the collar. Kunal sees this and fights with Vandana. He decides to get revenge and so he buys their house and kicks them out. He agrees to let her family stay there only if she becomes his assistant. Mrunal and Vaibhav start an affair. Kunal finds out and wants to tell Vandana but can't find any opportunities to. Anagha and Hemant find out but decide not to tell her as she is the lone supporter for her father not to sell the house. Hemant is in debt and if they can sell the house, they will have enough money to pay off the debt. Vandana's aunt finds out about Mrunal and Vaibhav's affair but doesn't tell her. Instead, she begs Vaibhav not to continue the affair. He promises her but continues to do so.
Kunal overhears Mrunal and Vaibhav talking about how they plan to get married the next day, the supposed day of Vandana and Vaibhav's wedding. Kunal brings Vandana to the temple where Mrunal and Vaibhav will marry but they're not there. Vaibhav and Vandana marry and Vandana asks Kunal not to get involved in her life. As a tradition, Vandana's family goes to Vaibhav's house. Vandana faints and it turns out she can't be a mother. She walks out of her house in a daze and meets Kunal and Bobby on the road. Kunal, Bobby, and Vandana go to work together and Vandana sees a little girl named Tara on the road. She is almost hit by a car but Kunal and Vandana save her. Tara is revealed to be Kunal's daughter meanwhile Tara and Vandana bond. Later that day, Soniya and Indraneel, Kunal's wife and his former best friend, show up and declare that Soniya wants a divorce from Kunal to marry Indraneel and wishes that Tara live with Kunal. Kunal refuses to accept Tara and Vandana takes care of her. Kunal can't bear to be a father and brings the child back to Soniya's house. Tara runs away from home and is kidnapped but Kunal and Vandana save her. Kunal decides that Soniya isn't responsible and decides to take care of Tara himself. Kunal accepts Tara and Soniya and Kunal gets a divorce.
Vandana learns of the affair and divorces Vaibhav and expels Mrunal from the house. Soniya accuses Kunal and Vandana of having an affair and blames it on Vaibhav and Mrunal. Kunal and Vandana get into a fight and he forbids her from meeting Tara. Later, Tara has an allergic reaction to peanut butter. Kunal is unable to take care of her as he intoxicated, but Vandana finds her and takes her to the hospital. Kunal realizes Vandana will be a good fit for Tara as a mother. Vandana and Kunal decide to get married. Vaibhav and Anagha attempt to kill Vijay to get the property. Vandana finds out and has the police arrest Vaibhav while Anagha does not get exposed. Vijay refuses to accept Kunal as his son-in-law and states that if Vandana were to marry him, he would disown her. Mrunal, mad about Vaibhav being in jail, makes a deal with Soniya. Soniya will pay Vaibhav's bail in exchange for Mrunal morphing nude photos of Vandana. Vandana is harassed in public but Kunal protects her and figures out Mrunal and Soniya leaked the fake photos. Indraneel decides to move to Dubai with Soniya. Kuldeep learns of Kunal's marriage and decides to stop it along with Pammi. He calls Kunal back to London for six months.
6 months later
Kunal returns to India and marries Vandana. Soniya arrives and reveals that Indraneel hits her. Kunal lets Soniya stay at the Malhotra House, after it is revealed that Indraneel abuses her. She becomes jealous of Kunal and Vandana's budding relationship and takes Pammi's help with destroying their relationship. Tara has a panic attack at her birthday party and Kunal blames Vandana and calls her a bad mother. Vandana receives a call from the Karmarkar house and finds Mrunal trying to kill herself. Vandana tries to find out the reason but Mrunal confesses she’s pregnant. The next day, Vijay expels her out of the house. Vandana proves herself to be a good mother and Kunal apologizes.
Kunal and Vandana hit a woman with their car and it turns out to be Vani, Kunal's mother. Kunal's father, Kuldeep, had sent her to a mental asylum and told his children that Vani had left for good. Vani has lost her memory and is now staying at the Malhotra House. Considering his father to be a god, Kunal always listens to Kuldeep without ever doubting him, therefore hating his mother. Knowing her mother is innocent, Vedika, Kunal's sister stays at the Malhotra house to support Vani. Mrunal and Bobby elope and return married claiming to be in love, with Bobby having accepted Mrunal's unborn child. It is revealed that Mrunal plans on deceiving Bobby after getting money and jewellery and run away with Vaibhav. Gradually, Kunal and Vandana grow closer and fall in love and consummate their marriage. Mrunal has a miscarriage and blames Vandana, accusing her of being jealous because Vaibhav chose her and that she can never conceive, to which the Malhotras find shocking. Later, Vandana and Kunal separate due to differences created by Kuldeep, who constantly harasses Vani. To make ends meet, Vandana sings in bars and eventually finds out she is pregnant. She tells Kunal but doesn't reconcile with him. Mrunal steals money and valuables from the house but returns when she sees Vaibhav's true colours. Vani regains her memory and tries telling Kunal, but Kuldeep attacks her. They fight, but Tara is injured in the process and one of her organs collapse. Vandana donates hers but doesn't make through the surgery. She is later revived with Kunal's love and they reconcile. Kunal and the Malhotras leave the house after a confrontation with Kuldeep. They all move in with the Karmarkars and 3 months later, they all prepare for a festival and the show ends on a good note.
