Either Preethi will end with Nandu or if CVs have way they will just get her together with Mohit. But Nandu's this one dialogue got me thinking "Pyar karna alag baat but nibhana alag". There should be for something Nandu's character is brought in the show.
Or as someone made a post on this interpretation...
Either Vyom's marriage will get fixed with Preethi and Nimmi at the end will take her place.
Either Vyom at last minute will run away with Pari, and Nimmi or Preethi will end up marrying Sujeev.
But I strongly feel Preethi will end up with Nandu.
