Actually in 1st season tara & deep were endgame because of from beginning alisha & arjun had made strong fan followers by their chemistry whether it's arushi & deep or tara & deep. As tara & arohi was acted by same actress so fans didn't have any problem with endgame. But nia's entry as arohi was never accepted by fans. Though I did not watch 1st season but I knew about fans hue & cry regarding nia's entry as arohi & fans over turn wanted the unite of tara & deep because tara role was still acted by alisha. & cvs did it. Now endgame of immj 2 also dependant on whom most of fans want that I think.
Agreed, like I said Arjun-Alisha chemistry was there be it Deep-Arohi or Deep-Tara which isn't why it wasn't hard to accept them as end pair as they were seen some way or the other together throughout the series. But here I can't see RidBir, even if later on the show they do that Riddhima going back to Kabir and put more scenes of them... for me it will be tainted with RiAnsh chemistry which is going on plus the fact that after this when Riddhima goes back to Kabir, she won't be as she was in the beginning of the show. Somehow when she returns, she will have Vansh's influence on her which would definitely be seen and affect Riddhima-Kabir... So, really rooting RiAnsh and let's keep fingers crossed I guess...
