Jhanvi...( because he loves Ganga as he feels for her )
Then you all wrong.
He is only doing that for Pure care; respect and concern.
Otherwise he would have forcefully married Ganga itself since he is soo concern
And u all feel he sacrifice for he loves her.
No simple
Ganga is kind of high dominating side & no man including Sagar may cherish it.
Probably he may not love jhanvi as much as he does for ganga
But he would prefer her as wife as a little timider types
( llook at way ganga roughly climbed the wall and smashed anaesthesised Saloni)
Be it even for good...i dont think so Sagar would prefer anyone like thaat as his life partner
Pantherous types...
So he will always love her and sulk all life but his official bride lifelong will be Jhanvi or someone
Else
&
Not the Gangaa.
Ideally...they would want Morale to be shown to all child widows is get well educated than stay love love love tossed and keep waiting and mala japping.
