To me Deepveer seem a bit too OTT to be genuine tbh I wonder if RS is this hyper about his adoration for her outside the camera frame as well. But nevertheless, whether he loves DP genuinely or not, he at least has this sense that he should respect his wife & never ever belittle her publicly. So there's at least this understanding & a feel of mutual respect between them. You can have n number of problems between you but in front of the outside world you should be viewed as a united team.
But in case of RK-Alia it somewhat seems like Alia is obsessed with RK & RK doesn't really care about presenting any united front to the outside world. He doesn't have to be so touchy or so hyper like RS but at least respecting his wife publicly is a basic courtesy, which he sometimes doesn't bother with.
