Is Nihals reentry2 revive Su-Ni Romance?

Do u th8ink that Nihal has been made to re-enter because the producers have planned nihal-suhana chemistry again and their union this time...or its just a side track introduced for sometime to move the story for sometime...and finally suhana will remain with dev.
What do u feel, is the actual motive of bringing back orignal nihal i.e bhanujeet and not amit tandon and orignal suhana i.e rucha and not kanchi.
