I donno about Anu (that's still in future to come) , but as for now Radha is NOT Samrat's wife . First of all that candle light phere with no rituals , no witness , no registration is NOT marriage. Radha is a naive village girl & most probably uneducated , so she's considering that as marriage, but in reality there was no marriage between her n Rat .
Secondly Samrat already has a legal wife (Urmi) , though he's in middle of a divorce, he's still married & can't marry again. Radha in no way is Rat's wife . She's very naive, nope , actually very foolish to think she's become Mrs. Samrat Singh Rathore đ„±
