As we all r guessing from day1 maybe ISHANA and ANIKA r sisters and they r related to 20year mystery of oberoi
Then what's my point is that Shiva wedding should take place with ANIKA and on the wedding day ANIKA come across something related to the link of her past and oberoi and go from there
All would get anxious that where she has gone and she make dhasu entry with police and inform about it and this way reveal her real identity and make senior oberoi arrested and then there would be lot of Tasha between Shiva
And the news of oberoi and ANIKA should reach all over and ISHANA and get the news and then she get to know about her sister and then when ANIKA would be discussing about her sister she would make dhasu entry and reveal her identity shocking on and again give lecture to on
And in this way ANIKA would have some relation with Shiva and indirectly with oberoi which she can't break easily and ISHANA would also be now related and part of this story
And there would be lot of tashan and fight between ishkara and shivika and adjust these there real love story would start
And even on come to know about rishi a and thus lead to her goodbye
