Shimla our manali

Did they shoot for immj in manali before which ep date they shot in shimla how come arohi was so shocked to hear manali she was from shimla in the show as well how come arohi never mentioned that she has been to manali in the show she never said our they just acted that all of it is shimla in show

They mentioned off screen some scenes were in manali
So in show they only mentioned shimla not manali
That vishal was murdered in manali
Because manali and shimla are different
Our did they just acted that it is all shimla
