I will be happy if siddhi is doing this as a part of torturing Kunal. But I don't like her dancing with Abhay so happily. Also, I sense a repeat of Ishq Sufiana here! Like Rush said, I want siddhi to push him away if he is going to be rude with her.
@Noreen, I know she saw Kunal with the vamp a couple of times but Kunal did not do it deliberately to hurt Siddhi. He was drunk and did not even know Siddhi was watching them. Here, I feel bad for him because she is deliberately dancing happily with Abhay infront of him.
