I don't know if the topic was meant to be offensive or not. All I know is that it is all edited and made to look like what we see for drama. They all share great rapport with each other be it Amruta, Karishma, Sana, or whoever. They are getting along well so why are their fans arguing and attacking each other. And whatever was said about Sana not being interested in Amruta's friendship was so not needed at all. They all are very happy and excited for each other so don't judge. Like I can give examples showing that HiMruta and UpMa have absolutely no problem with each other.
Exhibit A: When Amu started crying after the Manwa Laage performance, did anyone notice Karishma's reaction. She felt really upset for Amu and has always appreciated her.
Exhibit B: When the couples were playing the love/wed/kill game, Himanshoo had said he would kill Karishma and Amu hugged her and said "aiyoo kyon, not Karu!"
