The story begins with Madhav Jha, a boy from Dumraon, Bihar, as he comes to meet the author Chetan Bhagat and leaves behind a few journals from his half-girlfriend who he thinks to have died. When the author calls him back the following morning to narrate his story, he begins with his struggles to deal with students in St. Stephen's College.

The rich and beautiful Riya Somani, a girl from Delhi, is also selected through the sports quota. Meeting her, as he would call it a twist of fate Madhav and Riya become close friends due to their association with basketball. Madhav always wants to make her his girlfriend, which she refuses. Desperate to get physical with Riya, he demands to get physical with her. Offended by his obscene ultimatum(Deti hai to de, warna katle), Riya parts company with him and warns him not to talk to her any more.

A year later, Riya marries her childhood friend Rohan and settles in London where Rohan has a big business. Finding Delhi unbearable on grounds of losing Riya due to his own fault, Madhav decides to settle in his hometown and help his mother, Rani sahiba with her school. Seeing the condition of the school – no proper classes or toilets – Madhav decides to meet local MLA Ojha for financial help, but MLA is of no help. An opportunity comes when Ojha informs him of Bill Gates' visit to some schools in Bihar. Madhav tries his best to convince Gates to fund his schools' development, but in order to do so he has to prepare a speech, preferably in English.

In the course of his struggle, he comes across Riya, who was already a divorcee. As Madhav is in a fix as to how he would prepare the speech, Riya helps him. The two are successful in their fundraising, but, after the speech, Riya leaves a letter for him which says that she has lung cancer. With three months left to live, Riya leaves for New York to become a singer, a dream she wanted to pursue. After three years, it is revealed from Riya's journals that she is alive. Riya left no trace of her in India. Madhav goes in search of her in New York and stays in his friend Shailesh's apartment. After three months of extensively searching, he finds her in a bar working as a singer, two days before leaving for India. They two marry and the story sets off.

The book ends as the author visits the rural school in Dumraon three and a half years later; he discovers it is being run successfully by Madhav and Riya, who now had a son, Shyam.
