The film follows the love triangle of 3 childhood friends: Pooja (Mukerji), Raj (Roshan) and Tina (Kapoor).

marked the directorial debut of Kohli, who also wrote the dialogue and co-wrote the screenplay and story with Aditya Chopra.

The film's cinematography was jointly handled by Ravi K. Chandran and Gopal Shah, while Rahul Sharma served as the soundtrack composer.

Raj takes Pooja to his favorite church, and she accidentally hums the tune of a song he wrote for her many years ago.

Hearing this, Raj instantly realises that Pooja is the one who had been writing to him all those years and remembers all the little things he had shared in the e-mails that she knows about.

Pooja agrees to marry Rohan to satisfy Raj's ultimatum and ensure Tina's happiness.

At the altar, Tina confronts Raj and Pooja, saying that she is not alone and is glad to have such great friends who are willing to sacrifice their love for her.

[7] The media reported that the film was based on the 1996 American romantic comedy The Truth About Cats & Dogs, but Kohli explained that "not one scene from it is the same.

[14] Mukherji, who features as Pooja Sahani, said that she "loved every moment of working" on Mujhse Dosti Karoge!, and described the film as a "privilege" for her.

"[16] Roshan portrays Raj Khanna, a part that he compared with his role in Kaho Naa... Pyaar Hai (2000).

[18] She found the role to be "very glamorous, typical of what people would expect of me", and believed that her fans, especially male, would like it.

To prepare for her introductory scene, the actress did not eat for 3–4 days (this was inconsistently reported)[9] as she wanted to "look great as it involved exposing my midriff".

[25][26] The lyrics were written by Anand Bakshi, with vocals performed by Alisha Chinai, Alka Yagnik, Asha Bhosle, Lata Mangeshkar, Udit Narayan, and Sonu Nigam.

[28][29] The soundtrack received mixed reviews from music critics;[31] Narendra Kusnur of Mid-Day called it "hummable", and wrote, "Rahul's orchestration style is youthful, and the use of guitars is interesting and innovative."

Kusnur, however, felt that "some songs have that typical [Yash] Chopra['s] banner flavour that has become very predictable and hackneyed of late".

[32] In a review published in the entertainment portal Bollywood Hungama, Joginder Tuteja believed that Sharma "does a superb job in churning out a number of melodies in one single package".

"[34] According to the film-trade website Box Office India, with around 1.2 million units sold, the soundtrack became the eleventh highest-selling music album of the year.

[31] Writing for Bollywood Hungama, Taran Adarsh gave the film a rating of 1 star, noting that it "clearly belongs to Mukherji, who has the meatiest role comparatively".

He believed that Mukherji was "superb in a role that fits her like a glove", but thought that Kapoor was "relegated to the background completely".

[42] In a 2.5 star review, Subhash K. Jha saw that "Kohli tries hard to bring in his own touch to the [Yash] Chopra-esque ambience".

[44] Manish Gajjar of the BBC shared similar thoughts of Kapoor: "[She] as Tina looks ravishingly beautiful and shows great flair for comedy in this film.

Although the audience will be reminded of her character of Poo from Kabhie Khushi Kabhie Gham...."[45] Outlook magazine's Namrata Joshi, who rated the film 1 star, declared it as "avoidable"; she was highly critical of Roshan, who she deemed "makes a poor parody of himself".

"[47] Madhureeta Mukherjee of The Times of India claimed that Mukherji "scores almost full marks for her heart-rending performance",[48] with Empire's Omar Ahmed appreciated her for "saving" the film.

[49] Khalid Mohammed observed of Kapoor: "Of the cast, [She] is reliably spry and saucy but should take care not to repeat her hoity-toity act if she is to escape typecasting.

"[50] S. Ramachandran from Mid-Day wrote that "Despite its numerous flaws, a fabulous performance by Roshan, an emotionally-powered role from Mukherji and a sporadically-intense act from Kapoor drive the film".

[51] Stardust hailed, "Though Kohli has handled some scenes with sensitivity and maturity he fails in many others, which gives the feeling of déjà vu.
