One year later Karan's cartoon Hum Tum becomes a hit and he writes a book about Hum and Tum. Karan realises his mistake and tries to seek her out but fails. Rhea leaves him since Karan projects his confused feelings as guilt rather than love for her. Rhea becomes upset, as she did not consider their actions a mistake she realizes she loves him but tells Karan that they should not commit one more mistake by marrying for the wrong reasons. Karan deems it a mistake and asks Rhea to marry him as he feels he took advantage of her, and that marriage will rectify the mistake. That night Rhea and Karan consummate their relationship. Mihir makes Rhea realize hers and Karan's love for each other. On the engagement night, Rhea learns from drunk Diana about the conspiracy and gets upset with Karan. But eventually Mihir falls in love with a friend of Karan's, Diana Fernandez ( Isha Koppikar) and they get engaged. Sensing that she needs to be with a strait-laced, "boring guy," he conspires with Bobby to fix her up with his shy best friend, Mihir Vora ( Jimmy Sheirgill). Karan returns to Mumbai, and three months later, Rhea and Bobby visit. He learns from Rhea's mother Parminder "Bobby" Prakash ( Kirron Kher) that Sameer has died in a car accident, and he sets out to help her reclaim her positive outlook on life.

Years later in Paris, Karan is visiting his father Arjun ( Rishi Kapoor), when he runs into Rhea. They bicker again, but this time, they part on good terms. Rhea is marrying Sameer ( Abhishek Bachchan). Three years later, Karan is helping his mother plan a wedding that turns out to be Rhea's. After six months, he spots her in a park in New York, and he makes a scene with his girlfriend Shalini ( Shenaz Treasurywala), who turns out to be Rhea's childhood friend, which ends in their break-up. Outraged, Rhea slaps him, and storms off, but Karan insists they'll meet again. He ends their contentious time together with an unwelcome kiss. Karan quickly learns he has little in common with the feisty but proper Rhea, but he won't give up. His feeble attempts at flirting go nowhere, but when they have a stopover in Amsterdam, she agrees to explore the city with him. On a plane from Delhi to New York, he meets Rhea Prakash ( Rani Mukherjee) who doesn't seem to be interested in him. His daily comic, named " Hum Tum," explores the battle of male/female behavior. Karan Kapoor ( Saif Ali Khan) is a cartoonist and a self-styled ladies' man. At the 52nd National Film Awards in 2005, Khan was awarded the National Film Award for Best Actor. Hum Tum received 7 nominations at the 50th Filmfare Awards and won 5 awards, including Best Director (Kohli), Best Actress (Mukherjee), Best Comedian (Khan), Best Female Playback Singer ( Alka Yagnik), and Best Scene of the Year. It received mixed-to-positive, with praise for its direction and performances, but criticism for its script. It was the seventh highest-grossing film of that year. The film had an above-average opening and did fairly well at the box office, with a gross of ₹315 million (US$4.2 million). The special effects were done by Tata Elxsi. The film features several short animation sequences, which were created by Kathaa Animations headed by Prakash Nambiar. Over many years and countless run-ins, the two despise each other, befriend each other, and fall in love with each other-in no particular order. Hum Tum follows the encounters of two people who run into each other on several occasions under circumstances ranging from friendly to hostile to cordial to loving.

Produced by Aditya Chopra under Yash Raj Films, the film stars Saif Ali Khan and Rani Mukherji.
