I dont get it ! If Gunjan doesnt show her concern, she is considered selfish, and when she does, she is considered a problem !! Bui had already said that Mayank was a fraud in front of her, so infact by saying this, she actually went ahead and ruined her image in front of Bui, because Bui was shocked that even Gunjan could hide something like this, and she did all this because of her love and concern for Nupur. I guess whatever Gunjan does is always wrong !!
