ruhi s legal custody is with ishu. even if she would not be married to raman. because raman and shagun both are now not good for ruhi.
personally I want ruhi too turning to shagun even just for drama. because raman hardly matters for her. she likes to give ignorance to him.only then she will realize she is losing ruhi too for adi and shagun. she had taken ruhi too granted and sent her to shagun for one night stay and forced her to attend wedding functions to make shagun happy
