I dont think she has really left. She is hurt that he doesn't come for pooja so must have gone to one of their fav places to cry buckets. Kunal will soon reach there, console , talk abt their sacha pyar and bam! she will be back home in his arms.😆
I think the flower wala scene will come after that.Remember sakti saying that he gives her a flower coz he couldnt be there with her during pooja
There was a link which showed Kunal seed many missed calls of N n rushed to meet her.. watchman said something... Caption of the link said Nandini left..
