I am sorry to say so but i have explanantion for this.I am a telugu girl from andhra and acc to our culture and family traditions ,rachana and gunjan mothers are sisters.So they too are sisters.Since rachana is sister to mayank,gunjan will also be a sister to mayank. Never we can think like tht.
After seeing this show,I and my family were like how can these ppl show a brother (be it cousin) fall in love with his sister?
I am nt aware much about the traditions and family cultures in north or prevailing in hindi or marathi origin ppl.
This post i just would like to share my feeling only.Plz dnt misunderstand
