Rani Di I don't think Guddu is using Runjhun's bhaag as he has fallen for her much before the secret of R being bhagaobwali was exposed. And also Amma has tried hard to convince G about the truth since he didn't believe the bhagonwali stuff. Also till now we haven't seen G experimenting R's bhaag as Shashi's brother (remember the boy R was supposed to marry with) did with the lottery ticket as a proof and it's the same for the M&Ms who always used her bhaag for their own benefit. It can also be said that R's bhaag hasn't been for automatic for G as he had worked hard for his mobile business to be a success as it hasn't flourished overnite.
I think R will have to understand this later on and also figure out the difference between her evils M&Ms and Guddu. The evils are not only using her but also are very mean n cruel to her whereas G's love is sincere and he is there to protect her from the cruel world as Amma has said before it's only Guddu could be her saviour. Even if G is hidding the truth, he is just following Amma's advice as he wanted to reveal it before starting his new life with R. It's obvious R's bhaag will follow G wherever he goes as they married and it is true that R's bhaag has helped G to become a changed and more responsible person. Unless after the revelation R wants her bhaag to benefit her M&Ms only as she feel indebted to them and for that she will have to break her marriage and return to PN and it will be so unfair towards G as he doesn't deserve it.
Pri, Sorry about the confusion, I do think Guddu is sincere now as well. I was just referring back to the last time he was nice to Runjhun and it turned out to be a ruse. I hope Runjhun does come to realize that Guddu is not using her exactly like you say that he hasn't tried to get her to do things that will help him profit. The M&Ms on the other hand make her touch everything so everything prospers. I'm also glad that the IM center did well slowly but Mittho even twisted that by saying how it went from selling nothing to doing proper business. How can Runjhun forget all the work they did to make the business take off? Advertising... teaching Guddu how to work with customers... giving discounts... and then also buying the other cellphones from the wholesaler. That wasn't just luck.
@bold: Completely agree. Maybe if she does choose her M&Ms she will notice that it doesn't matter if she is with them because her bhaag is now with Guddu.
