Varun: Varun is an ace student and an achiever in sports and other activities. He wants to live up to his brothers' expectations and sacrifices a lot for him. He's very sure about the kind of girl he wants to be with but cannot stand the blonde and gossipy variety, which happens to be exactly as Roshni is. And no matter how much he runs, fate and the girl keep ensuring that he does fall for her, and then when the truth comes out he's shattered.
Roshni: She is the baby of the family. A spoilt brat and acts like a princess. She is a hardcore romantic and lives in a world of her own. She's always looking for Mr. Right, but so far has only found Mr. Wrong. She is used to a lot of attention from boys and surprised when she doesn't get any from Varun.
