What If ?

I’ve just seen the episode where the chachi talked about Vansh past that something happened to him. I’m thinking what if Vansh liked someone and something bad happened and maybe Kabir is related to it. What if the girl that Vansh liked is a lookalike of Riddhima ?or has similar traits like Riddhima which is the reason why Kabir sent Riddhima for the mission ?. 

If we remember in the first episode Vansh the way he looked at Riddhima also he never said anything to Riddhima when she talks back as if someone else had done that they would have been dead by now. 

Yes I agree !! I think he’s attracted to her and also a bit obbessed with her 

May be. Because vansh doesn't love ridhima. But there is no doubt that he likes her and obsessed with her. The way he looks at her proves the theory. He becomes upset whenever he sees the engagement ring .
