Cabir will I guess. But where Raghav is not a part of fab5 and doesnt affect them on a personal level, Nandini has been at war with the fab5 regularly and I think Cabir likes her spirit but Cabir is friends with Alya, who will be severely affected with MaNan and hates Nandu and he is friends with Mukti, who again is Alya's best friend and hated Nandu and Dhruv, who well, loves both Manik and Nandu and will be heartbroken?
It is hard to assume anything, since it is too soon to guess what will happen ...
