Ok I still do not believe that Mihir is the culprit but I think we still have a big issue here. Mihir is shagun's brother and many of us know this for a while now. BUT Ishita,Mihika and Iyer family still has no clue about it. I do not understand that how can MIhir hide this information from Mihika and it will be no less shock for Ishita that Raman hid such a big thing from her. She would be upset and I think rightly so..even if Mihir broke all relations with Shagun after her divorce, how can he hide such a big truth from his would be wife and her family!! It could be a cause of rift between Ishra and mihir-Mihika..What do you guys think?
