Case1: Misty hated kripa because, kripa left prithvi crying at their engagement. And what did Misty do at her engagement to kartik. Exactly.
Case2: Kripa hated the person who the person who seperated angad and her. But what did she try to do with that fake girlfriend of Zaib. Exactly.
Case3: Naina hated kripa for some reason, and now she had turned into a crying mother because she has been seperated from her son. She did this to kripa before, so she is in kripa's shoes now.
Case4: Angad hated his family for manipulating him and turning him against kripa. He hated them for using him. But what is he doing now, manipulating misty and using her for his own purpose. (I agree he had different motive but same action).
Case5: (My favorite) Prithvi hated Angad because he thought angad took his love, kripa away from him. But what does Prithvi do, he turns around and takes everything away from Angad including his love.
