I think the storyline is developing - its ok actually. The trouble is some viewers want to see their hearthrob actor or actress in a particular way and if that does not happen they say the storyline is bad. I actually don't think it is bad.
Your have Ranveer - a person out to seek his pot of gold in London and is not above breaking a couple of hearts to achieve i. Whose ethics are somewhat questionable.
You have Sahiba - a girl who is totally in love with Ranveer - who is wiling to see him achieve his goals and willing to sacrifice whatever is needed. But you also have a Sahiba who has a conscience - althoug her heart and soul is on Ranveer - she does feel some pricks of conscience of letting Daljeet and his mother down - she is starting to break out of her "i love Ranveer at any cost" to "is getting a love at any cost right?"
YOu have Daljeet - a simple chap who was already in love with Sahiba before they even came to London - he was living in a fool's paradise while in India - not realising Sahiba is not for his for the taking...a Daljeet who is kind hearted and who thinks for others because he probably feels he can cope with rejection but wants to ensure others are happy... a Daljeet who has a heart of gold ... here I hope Daljeet's character will evolve to be more self-confident.
YOu have Jazz - a spoilt brat of a rich girl who has done everything wrong that can be done wrong - but who is failling in love with an opportuniist, Ranveer.
Nice story what...!!!!
