i think it is not raunak cuz in all ekta shows if the heroine is supporting then he is the murderer but if she believes he is the murderer then he is not...
a)if he was the killer ... kasturi wud buy his sob story that he is innocent and he wildered that he broke her trust
b)if he wasn't the murderer...kasturi wud throw him in jail then when she finds out she becomes guilty then tries to bail raunak out
wat do u guys think???please post your replies...
