Well according to me both sandy and meghna are at fault I would prefer if both stays away from karan
Meghna has unintentionally hurt karan nd she is going to regret it alot later
It's time karan takes a stand for his love and tries to find solution of his disease so that next time nobody dares to separate him from his life a.k.a naina
And I hope that this separation will be enough for naina to realize how much karan means to her and how she cannot live without her and how it is necessary to punish massi ma for them to have a normal life
