I have never watched an Indian serial before PHS so do not know what other shows are showing.
We live in the 21st century and India is fast becoming one of the worlds leading countries. So in this day and age there is no MORAL reason why a woman should be involved with 2 men of the same family. Some relationships are OFF LIMITS and this is one of those relationships especially when you consider that Adi is an educated yound man who used to livein Delhi so should be more progressive in his thinking.
