Rajiv (Shahid Kapoor) wants to be one of the popular kids of his college. However, due to the lack of a girlfriend, Danny (Shabhi) and Javed (Kapil Jhaveri) mock him and his best friend Mambo. Javed and Danny plan a trip to Alibagh and invite Rajiv and Mambo only on condition that they come along with girls. Rajiv decides to ask Payal (Amrita Rao), his reserved childhood friend to become his girlfriend and tells her that he's in love with her. He does that only for the trip as he doesn't believe in love and serious relationships. Payal returns her "feelings" and agrees, as she has been in love with him since their school days. Both of them start spending time with each other and Rajiv gets to know that Payal really loves him. Then comes the time for the trip and by some persuasion, Payal is allowed by her father to go. Both of them accompany Danny, Javed and their girlfriends and stay at Danny's beach house; however, Rajiv's drink is laced by Danny and, being intoxicated, he behaves badly with Payal. Payal realizes that Rajiv doesn't love her and slaps him. After the midnight picnic incident,Danny and Javed's girlfriends try to clear misunderstanding by making Payal understand that Danny was the reason for Rajiv's misbehavior at drunken state,so Rajiv wasn't at fault. Rajiv doesn't accept her apology and asks her to kiss him in front of everyone. Payal refuses saying that she doesn't need to prove her love by doing such a cheap act.Their relationship falls apart and Rajiv challenges that he'll have the most beautiful girlfriend of the college. Rajiv's best friend Mambo(Vishal Malhotra),who was in support of Rajiv and Payal's friendly relation, does not like this and insists that he gets back with Payal. But Rajiv rebukes him.

Soon after, Alisha Sahay (Shenaz Treasurywala), a stylish and beautiful girl, starts at Spencer College. Rajiv is smitten by her and manages to woo her with the help of his friend Love Guru (Yash Tonk). Meanwhile, Mambo and Payal become close,Mambo tries to cheer her up and be with her always. Payal still cares a lot for Rajiv and is silently hurt at seeing Alisha and Rajiv together. Nevertheless, she continues to talk to Rajiv and wish him a happy birthday. Rajiv is taken aback by the fact that it was Payal and not Alisha who bothered to wish him first, as Alisha is busy with her modelling shoot. Rajiv starts noticing that Payal and Mambo are coming close which irks him. Rajiv is surprised to find Payal at his birthday party in a pub. Payal gets emotional and tells him she now thinks that her views about love were wrong and that is why Rajiv is so happy with Alisha, something which was not with Payal. Mambo and Rajiv come to blows because of Payal, and Alisha slowly starts disliking Payal. The final straw is when Alisha sees Rajiv and Payal talking, and she learns from a mutual friend that they were together before she entered the college. She confronts Payal, behaves rudely with her, and accuses her of stealing her boyfriend. Mambo tries to defend Payal, and Alisha puts him off, which infuriates him. Rajiv and Mambo get into a fist fight. Alisha and Rajiv leave with everyone accusing him of fighting with his friends. At Alisha's flat, Rajiv is unable to think of anything else but how Payal loved him and he let her go, and how after their break up, she still cared for him, and the recent fight. Alisha gets insecure and keeps asking him to profess his love. He,imagining Alisha to be Payal, hugs her and says "I love you, Payal".

At the Farewell party of the college, Rajiv apologizes to Mambo with a thought that Mambo was planning to propose to Payal. He then realizes his mistake as Payal still loves him and Mambo was just being her friend. Rajiv tries to apologize to Payal but she doesn't listen to him. Rajiv then takes the mic and publicly apologizes to Payal. He tells her he loves her a lot, even though she might not believe him. Payal is still angry with him and tells him that doing a drama in front of everyone and proclaiming his love is not going to make her relent. Rajiv stands before her and gazes pleadingly into her eyes. Payal is convinced that Rajiv does love her and embraces him. Alisha comes there and finds Rajiv and Payal dancing on a slow tune. She apologizes to Payal for her behavior and wishes them good luck. The movie ends with Rajiv and Payal's dance.
