I think sundaram is being selfish by keeping Kannas identity a secret.
Kannapan has the right to know, and i think when he finds out about kannan he is going to be even more mad at sundaram.
As for aravind he is also being selfish. But he has always been that way. I really feel sorry for Kannan. I wish Radhika would come back and get together with Kannan. But shes with that amer ( forgot his name)....
I think aravinds should be with rukku...he loves her even if he is a little possessive about it. Kannan doesnt seem to like her anymore...or maybe hes acting like that because he knows hes not her murai mapillai....
