That's what I'm scared ofAnd exactly the reason that I want them both, Nisha and Kabir, to develope feelings for each other before Kabir finds out about Viraj. And even if he wants to leave then, Nisha wouldn't let him, would she? She's stubborn and she won't allow Kabir to do that with her- she can decide for herself, after all.
Apparently Nisha would hide this from Kabir too according to the spoiler.. So high chance they both get to know after N and K really fall for each other.
