No one wants as we'll 😃
To be honest I never felt Surbhi such an important character She is not. I have a guess about future story: May be Harak and preeto will look for a match for Harman but they have to tell the bride's family what happened to the first wife. Then may be they will have no option and will think Surbhi to get marry with Harman. Harman won't agree definitely but may be preeto will make him agree by saying if he marries surbhi she will allow Soumya to stay in their house. I am not writer but just a wild guess😆
