Neev then jokes and that awkward moment comes when they were about to hug. They stop themselves because Neev is still in love wih her and it would be wrong to hug her knowing how he feels for her and Prachi stops herself because though she has moved on she knows he has still not done so and a hug may not be right knowing how he feels. The bond of friendship between them still remains but somewhere down the line the innocence of it is lost. So now they cannot be as natural around each other. I hope that make sense.
