omg why dears you all thinking this way
at first ektha decides to name him as anurag basu so taani was introduced in first epi as taani basu(that time ritesh was ritesh segupta).then they decided anurag basu is only from kzk so they changed the name into anurag ganguly .taani is married to anurag only.
ritesh is anurag's jiju ,taani married anurag in child hood it means taani is sister like to ritesh (actually the relationship is sister here)then how come ritesh can marry taani.its so wierd so am sure it wont happen
