ii)Ritesh, Ananya or Shekhar (Rash formula) poison Anu's mind against TaaNu marriage by saying that she is taking advantage of his emotions and is always hurting him in the process.
iii)Shekhar told Anu to marry Neha(whatever that girl's name is. This may sound mean, but I don't care who she is.) and break of marriage with Taani if he wants to ever have contact with her.
These are my random predictions...just tell me how they can turn out to be..
