without wedding also they can use the set vidya😆 no cross marriage.😛..as u said cross marriage happens for NeeRag only not SidYa so sid cant stay any way with them...but story have to move..in the same way it will go without cross marriagei think it will... unfortunately this time no SidNi...
major reason is technical actually - the major set where they do shooting is neel's place which erstwhile used to be DD's house so if SidNi only have to get marry then... not sure if i make any sense.. but leave... i think cross marriage will happen this time.
