Manan may spend night together at guest house

Yes, it is a possibility. Because according to article Nandini room is filled with water and according to promo manshad fight will take place. Hence it is quite impossible to Nandini stay in her room and even more impossible for manshad to stay at one room. So Aryamaan may stay with Harshad. Then Cabeer, Manik and Rishav may stay at one room. After this Nandini and Navya may share one room. But we know manan, they can not stay away from each other. Specially after such a tense situation, Nandini will go near to Manik to calm him down.

you are right it will be interesting to watch but the way track going don't think will share a room
