What if Nupur is pretending not to know Mayank, Gunjan, and Samrat because maybe she had a medical report that she's about to die or has a bad disease? You know, like what happened in Kis Desh with Prem thinking he's about to die and tries to distance himself from Heer as to not hurt her? But then everything turns out to be alright...I hope that's the reason...what do you guys think?
