Keerti upset with Sunny

Ok so can someone explain why keerti was upset with sunny? Wasnt she part of their plan to separate raghav and pallavi? So why all this? And when did she get upset?

Also when did she tell sunny that nothing should happen to Raghav? I dont remember that.

So she couldnt care less what happens to pallavi? A friend of hers and above that a woman just like her. How can she let sunny destroy pallavi?
