I'll just copy my message from a similar thread....
Naa re, I don't think Mayank is falling in love, he was sweet to Nupur but I don't think he showed any signs of attraction towards her as say Samrat does for Gunjan... He hasn't appreciated her beauty or check her out or anything
Mayank looked @ Nupur like that because he was genuinely surprised and impressed that Nupur actually did the project. He hadn't foreseen it @ all because he usually is astute in his judgements. This explains the sorta dazed look he had throughout the episode.
But love... it will take a lot of time for Mayank to actually fall in love with any girl, let alone Nupur. He's so focused on his studies and right now they're just on the route to friendship.
Plus am sure, before MayUr fall in love, the fact that Gunjan in actuality did the project will be revealed, which will leave Mayank more annoyed than ever....
And as I've reiterated, Mayank wont fall in love with Nupur because she did a school-project well. He will fall for Nupur because she is a complete foil to his personality!!! š This project is just a way to that.... š
