In the US, the actors write up a contract, which I am sure they do in India. But why do a lot of lead actors/actresses are allowed to leave their shows midway. They should have atleast a couple of years contract, the fans are the ones who suffer. Not to compare but the original Manav from Pavitra Ristha or Lovely from Mrs. Kaushik just up and went to Bollywood. KSG is a very talented, good looking, great actor, so with great success, great offers are bound to come his way. I do want him to succeed but not on the account of ever leaving Qubool Hai.
I was reading KSG's interview and how he mentioned that if he gets a good offer from Bollywood, he would leave Qubool Hai and Serials. He wants to advance his career, he didn't think he would return to Serials but did when Bollywood did not work out last time.
Please let me know if I am assuming anything on the part of Indian contracts.
