Satyaprem alias Sattu (Kartik Aaryan) is a happy-go-lucky young man who lives with his middle-class Gujarati family in Ahmedabad. He has failed his law degree and dreams of getting married to a beautiful girl but always gets rejected for being jobless. At a function, Sattu gets mesmerized on seeing the dance of a girl named Katha (Kiara Advani). However, he is heartbroken on learning that she is already in a relationship with a man named Tapan (Arjun Aneja). Sattu lives with his parents Narayan (Gajraj Rao) & Diwali (Supriya Pathak). His sister is Sejal (Shikha Talsania). Doodhiya (Rajpal Yadav) is their milkman. Sejal runs a Zumba class in the studio room on the first floor of the house.

One year later, Sattu gets to know that Katha has broken up with Tapan. He visits the Navratri function again to see the dance of Katha with his father Narayan. There they meet Katha's father Harikishen (Siddharth Randeria), a wealthy businessman who owns a snack shop, along with her mother Rasna (Anuradha Patel) and her sister Kinjal (Maira Doshi). Dheeraj is Kinjal's fiance. On learning from them that Katha is sick, he goes to see her at her home, but is shocked as she tries to commit suicide by cutting her wrist. Feeling concerned, he rushes her to the hospital immediately. Katha recovers but gets angry on Sattu for saving her. Harikishen comes to see her, behaves rudely with her and scolds her, saying that she should have rather died. Later, Katha thanks Sattu through text messages. Sattu starts falling in love with Katha. Harikishen thanks Sattu for saving Katha's life, and is impressed when Sattu deals with the doctor, who tries to extort money from Harikishen for not reporting the suicide case to the police. Harikishen says that Katha wanted to commit suicide due to her break-up and her singing career going nowhere.

Sattu continues to visit Katha at her house, and is encouraged by her mother, who is looking for a suitable boy for Katha. After a few days, Katha's parents bring her marriage proposal to Sattu's house. Sattu becomes overjoyed and says yes to the marriage. Narayan is very happy and Sattu decides to stay with Katha in the upstairs studio. Katha is unhappy, but still reluctantly agrees as Harikishen threatens to kill himself if she does not get married. After marriage, Sattu tries to get intimate with Katha. But she is not interested in the marriage or getting intimate at all and is uncomfortable with sharing the same bed with Sattu. She says that the sound of his snoring disturbs her sleep. Sattu sleeps in a separate room every day and tries various remedies to fix his snoring problem. When even then Katha refuses to sleep with him, he angrily lashes out at her. Katha tells him that she is asexual and does not feel the desire to have sex, leaving Sattu in shock.

Frustrated, Sattu tells Harikishen that he wants to end the marriage and asks him to take Katha away. Harikishen advises him to give her some more time to warm up to him and try to make her feel comfortable. Going by the advice, Sattu tries to win her affection. He buys her gifts and takes her out on dates. Their relationship improves and Katha reveals that she had lied about being asexual. She encourages him to attempt the law examination again. Finally, one night they try to get intimate, but Katha has an emotional breakdown, due to a horrific incident in the past. It is revealed Tapan had forced himself on Katha the previous year after the function. She had become pregnant and also had to get an abortion. Her family knew about the incident but did not inform about it to anyone, fearing the shame it would bring for the family in the society which would tarnish their reputation and had disowned Katha. Due to the trauma, Katha does not feel comfortable in being intimate with anyone. Katha admits the entire truth in front of Narayan and Diwali. Diwali understands her agony and stops Narayan from confronting Harikishen.

Sattu is furious on hearing this and thrashes Tapan. Sattu tells Katha that he understands her pain and is glad that she is in his life. Now, that Katha has admitted the truth, she feels much lighter and finds a friend in the form of Sattu. Sattu and Katha leave for Kashmir for their honeymoon, now more deeply in love with each other, but Katha is still not comfortable to get intimate. Sattu understands her and gives her space to cope up with the situation. On the day of Satyanarayan Puja, Sattu registers an FIR against Tapan and encourages Katha to fight. The film ends with Sattu and Katha performing the Pooja and fighting together against Tapan in court while Sattu passes his law degree and Katha starts healing slowly with Sattu's support.
