Observing from initial episodes we have seen there is so much influence of Mahadev on Rangrasiya. It will not be wrong to say that Rangrasiya is a modern version of Om Namah Shivay.
So what happened in the story Mahadev was crude God but Sati changed him to a better person but due to some unfortunate event Sati died, Mahadev became literally insane then came Parvati into picture who after kadi tapasya got Mahadev as husband and she too changed him back to a better person.
So just replace Sati to Paro and Parvati to look alike, so basically Rangrasiya has become "OM Namah Shivay".
In future we will get some intense romance so cheer up guys, be positive, think positive and watch Rangrasiya they need us.
