His daily comic, named "Hum Tum," explores the battle of male/female behavior. On a plane from Delhi to New York, he meets Rhea Prakash (Rani Mukerji) who doesn't seem to be interested in him. His feeble attempts at flirting go nowhere, but when they have a stopover in Amsterdam, she agrees to explore the city with him. Karan quickly learns he has little in common with the feisty but proper Rhea, but he won't give up. He ends their contentious time together with an unwelcome kiss. Outraged, Rhea slaps him, and storms off, but Karan insists they'll meet again. 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. Three years later, Karan is helping his mother plan a wedding that turns out to be Rhea's. Rhea is marrying Sameer (Abhishek Bachchan). They bicker again, but this time, they part on good terms.
