Kyun! Ho Gaya Na ... und unsere Träume werden wahr

Die schöne Diya Malhotra zieht in das Haus des besten Freundes ihres Vaters, um dort zu lernen und um ihren Universitätsabschluss zu machen. Sie trifft dort auf Arjun, den Sohn des Hauses, in den sie sich nach kurzer Zeit verliebt. Dieser jedoch ist an der Liebe nicht interessiert und spielt Diya ständig Streiche. Als er zu weit geht, verlässt Diya das Haus und Arjun beginnt bald darauf zu merken, dass ihm Diya fehlt und er fasst den Entschluss ihr nachzureisen.

Diya (Aishwarya Rai) is an intelligent university student who does not agree with arranged marriage. She spends much of her time at an orphanage in Coorg, helping her "Uncle" (Amitabh Bachchan) with the kids living there. The story begins when Diya travels to Mumbai to take exams. While there, she stays with her father's friend, and meets their lighthearted son, Arjun (Vivek Oberoi). His views on love are completely opposite hers. But they start spending time with each other and soon fall in love. Arjun however, is unaware that he is in love, whereas Diya professes her love. Misunderstandings occur until Arjun ventures off to the orphanage, in hopes of putting a smile on her face again after breaking her heart. There, he realizes his true feelings for Diya, who is planning to marry her childhood friend, Ishaan (Suniel Shetty). Luckily, this was all just a plan 'Uncle' made to get Arjun to realize his mistake of not professing love for Diya at the right moment.
