After being so close with nisha during paper dance, he was into his own mode..!! he got so formal with her and confessed his lie...!!
i feel he felt her feelings for him( during the dance i'm not sure about the confession) and a sense of guilt moved him for lying her..!! so explained her in sweet way to not get angry on her mother..!!
I'm sure viraj whatever does with others has a purpose..!!
He recollected arthi today and shared his happiness..!! He is just pouring his emotions on her, just treating her as an outlet... which he used to do previously in the form of letters to his mother...!!
He told her that he is waiting for his mother to come into his life..!!
Too many speculations about viraj's mother..!! This is definitely a future track
So this is my conclusion about viraj:
He cares nisha... because she is his energy and strength for running the academy
He speaks to arthi.. because he needs an outlet...!!
On the whole VSR is a person who...
believes in love but doesn't believe in unconditional love... may because he never experienced it from childhood.. and that is why he never wish to pour his emotions randomly and controls himself to large extent and expresses emotions only with specific people...!!
I don't think VSR is greyish in doing that because it is obvious from a person who lead an isolated royal life to act in that way...
what you say guys.. please give me your opinion..!!
