Girls need more time, to get adjusted to new surroundings, with new responsibilities and the family........
nothing much changes for a boy......his life simply becomes more easy...he is in the same house, same surroundings and has someone in his room who he expects will take care of him and his things....
So, a girl needs more time off-work when getting married but Boys need the off only for the duration of honeymoon.......i don't think Rushad needs to leave the show because he is getting married....as Rucha needed....
