I have to admit Eijaz as Soham is good, he making the character his own.
I also have to say Soham and Reeva are good together, i think deep down somewhere in himself, Soham loves Reeva but doesnt tell her, and as we all know and could tell that Reeva loves Soham so much
I think Soham has got himself thinking that Reeva always goingf to be with him and has for 6 yrs so doesnt appreciate what he has with her, but i think if anything happened to her or she went away from him then he will realise
Or maybe Soham sees Reeva as trophy wife, a good looking girl on his arm at his so called doctor parites etc
