I don't think its her fault.
KD was like, "Mein apna naam boldunga but lets see ki ye Kiya apni friendship nibahti hai?"
Kiya ne apni friendship nibai (how do u spell it? Bolne me its very easy but when it comes to typing...grrr)She didn't tell to JJ when he asked, first. Second time me she had to! JJ blackmailed her!
So i don't think Kiya ki koi fault hai isme.
But i don't know what kd is thinking. Kyunki when KD saw Kiya and Kunal he started his 'plan' and now after this don't u think KD will do something?
