Actually i like her, now otherwise how will Arjun understand how good is Arohi or how will Arohi understand her feelings for Arjun. I think that's a good(EVIL) character she is playing which will help the story move on. Iam for it as long as it just helps Arjun-Arohi fall in love. Arjun-Nut marriage no way, that will be like killing the story. May be even if Arjun is engaged to Nuttasha, I wont mind, but no shaadi waddi plzzzz...thats too much. I think arjun will get engaged to nutasha becoz he will do anything for his dad, but then comes the catch, he cant marry her, Its his love for arohi which will force him to go against his dads wishes,and in this process Arjun-Arohi will understand each others love and express them.
I would like to say one thing here, we appreciate light only when we get to see darkness, we appreciate good only when we see evil. Same thing goes for Arjun Arohi, they will appreciate each others hearts and feelings, only when they are hit with something bad in others.
