Fortunately, there is another twist in the pipeline and Raman and Ishita are behind it.
In the coming episodes, Mihika will indeed accept Ashok's proposal for marriage leaving Mihir shell shocked. Shagun and Adi will also be left without any shelter and Raman and Ishita will once again extend a helping hand.
However, all this is just for saving Mihika form Ashok. On the wedding day, Shagun will replace Mihika as the bride while hiding her face in her ghoonghat.
