She is a pros and that's why got into trouble and Rudra saved her in past. The life & setting of Laila's house that was shown to us says the same. Her attitude and being a nachnewali she had many connection. But that does not mean that she can't love any one. A pros is also a human being and has every right to fall in love so did Laila. May be she gave time only to Rudra after she met him but Prostitution was her profession. That's what I get from the earlier episodes and that's my understanding.
Rudra did injustice or not that's not a point anymore because he is married now!But being a woman what she is doing is totally unjustifiable. That's why I don't feel sorry for her. There is a saying that Creating rift between married couple even shakes the heaven and hell! I was absolutely ok wth Tejawat, Mohini, Ladoo tracks but not this one! It makes me sick. I don't watch it on TV anymore, just go online watch everything except Laila lila and done with the epi.
