I used to watch kahin to milenge daily and know the story quite well. In that the girl who is playing the role of kritika is the main lead. 👏all others were sub lead. So, I think later kritika will be the main lead and slowly the story will revolve around her. Anyway, the girl who played kritika's role in Kahin to milenge is Aparna from kasauti zindagi ki (Anurag's third wife) and who played mishti/araina is Karishma tanna(Indu from ksbkbt). Apart from shashank there will be two other guys. both will be rich but one will be negative and other positive. the positive one will fall for kritika and she will fall for shashank but marry the other as she comes to know that her younger sister loves shashank. the two brothers did not have anythink much to do. the story only revolves around the two girls. but this time may be ekta will change a bit but don't think much as till now they showed almost same as ktm except addition of aairaina's sister coz in ktm she was the only child of the rich couple.
