Karan is just đ¤˘...his behavoiur towrads vidya is so nasty,he has no feelings of humanity atleast gaurav knows she has been hurt through no fault of hers...watch when gaurav's finds out karan lied about the phone call e.t.c he will go mad at him...
Uttara is sick,she knows its wrong,you can tell from a reactions but she still goes ahead...if she knows its wrong the best thing she can do is leave that house...
