What i feel about the situation is Siddhi is very straight forward type of girl... Its true that she is a lawyer and she should be knowing the crookedness of the world... but i guess the way she was brought up by her brother she does not exactly know how wicked the world can get...
Siddhi ko planning karna nahi aata... and never in her dreams she would have thought that Richa can stoop this low...
she believed in kunal... she knew he will not do anything wrong chahe jo bhi richa try kare...
She knew very well that kunal's concern for richa was just as a friend... she said this clearly when she confront Richa...
Issiliye usne challenge ko zyada seriously nahi liya...
Rahi baat kunal ka... even he is a straight forward guy... he trusted his friend Witcha... there was no chance that even kunal could control himself from falling prey to witcha's dirty games...
He would have slapped her if he was in his sense...
Both the wakil couple are good at heart aur unki achai ka nateeja bhukat rahe hei...
Ab dekhna yahi hei ki how are they gonna come out of this muskil situation...
and mushkilo se hi rishte aur mazboot hote hei... lets all chill out and watch how things are gonna turn around... As long as they love each other we should be happy...
