My Theory

I might be wrong or in a denial mode and may not bee accepting Mhika in a negative role but to me it seems that she's in on a plan with either Ishita (more likely) or all by herself.

That was I said it on another thread..
I'm also thinking the same that it's all mihika's plan..

All those rituals for mihika a two time divorce.
In ishu's case it was her 1st marriage when Raman wanted only a simple court marriage.
Why should Raman marry N oldie ?
If it was her plan what gave her the confidence that he would agree unless its their joint plan.
Even then if the simmi part is true Raman would either leave the place or give properties n money to simmi asking her to leave or admit her in a mental asylum.
If Raman is saving ishu this way as he knows the truth will be a strong possibility.
Or romi n mihika helping Raman in doing the same has a very high likelihood.
Romi ishu planning against Raman mihika planning for the same result is what I would like.
