I was also strongly suspecting Kasa Kaka... but when I read yesterday's update and shinybandi wrote that Fake Vansh asked Kasa Kaka to read Ichha's message to him, I thought Kasa was involved as he was helping Vansh read... I also thought that Kasa was there when Vansh signed his name so he should also know that he doesn't know how to read/write...
But when I saw the episode myself, I realised that Tiger didn't want Kasa to know that he's illiterate and he just kept asking him to read it as if he's already read it and wants Kasa to read what Icha's written about him... Wo keh raha tha "Dekhiye na kasa kaka... yeh Icha ne kya likh diya. Pata nahi kyun nahi samajhti... blah blah" jissey Kasa ko laga ke message parh kar wo doosron ko bata raha hai ke Icha ne kya likha hai!
Kasa started reading it quietly, then Tiger asked him to read it loudly so that Kasa doesn't know that he hasn't read the message.
Which shows that Kasa DOES NOT know that Fake Vansh cannot read!!
So now the problem is even more confusing.
I'm thinking CVs are themselves thinking of a plot in the meantime that's why they're going on a PATHETIC track about Icha stil being Vansh's wife.
Koi to drama chalta rehna chahiye jab tak wo aagey ki bekaar story sochein??
