How in the world can she be with someone like Rajiv for her life, I mean she sees that the guy has no patience. He's always thinking about himself and not the complete picture including the parents. He's reliant on his dad's shop. Does his dad even agree about Alka? Rather more apt to ask do his parents know about Alka?
Moreover, if a guy was coming to my house and forcing me to go with him, I'd call that kidnapping not eloping. I def wouldn't go or even think of defending a guy like that. Imagining if you're married to someone like that, in the long run the guy can even hurt you physically.
Now assume Alka does go with this guy. In life she not be happy as she will realize that story is way more a bed of thorns than roses.
