story of this show....???

can someone tell me the story of this show..i fail to understand why radhika is wears sindorr and yet clamis to be married to dev....and dev doesnt even know her.....m really confused.

dev sees radhika n falls in love with her but he doesn,t knoe her identity or anything so one day radhika n vishaka r together n dev asks one guy who is the girl n then radhika moves but vishakha is standing there n the guy says it,s vishakha n dev considers radhika vishakha. on the marriage vishkha runs away from home to become a actress but the producer tells her to bring money so she comes back n decides to get married to dev cuz after marriage she can run away with dev,s money. when vishakha is gone the amma makes radhikha the bride n dev n radhikha gets married but vishakha comes back n wears the bride dress n goes with dev to his house. dev sees her n doesn,t accept her but he is scared to loose his gradnma so he is just living with vishakha. dev doesn,t knoe radhikaha, name till today but he still loves her. radhikha is dev,s real wife so she wears the sindoor but she told dev she is married so yeah.

thanks so much..makes so much sense now..thns
