I feel riddhu is another arohi here.. vansh wanna find real culprit who harmed ragini.. he knows those ppl ll do same thing to riddhima if he get marry to her.. oh god.. he using riddhima as scapegoat to find ragini's culprit.. the thing s that did he act like loving riddhima n still in love with ragini or he just wanna find culprits only...Dunno.. as he said she is here for spl purpose in starting episode.. So this is that spl reason.. get her killed n find culprits n then live happily wit ragini...
