Yash is so much deep in the thoughts of Arpita that it will take some time for him to think about any other woman in those sense.
He has never allowed anyone to get closer to him as he so much wants to cling to his deceased wife. But Aarti is not allowing him to stay there and she some how manages to take care of him inspite of him saying no to her.
She just makes a way to do things for him. She just goes beyond the call of her duties and do the stuff for him and his daughters and his family.
So that makes her special and noticeable. She has a tendency to grow on you and without his realization he will start noticing and fall for her. but it will be a total denial in Yash's part as he thinks he cannot fall in love again and if he does it will be a betrayal to Arpita so he will fight it tooth and nails... but Yash has forgotten the word Destiniy. that Yash and Aarti destined to be together...
so let's see how CVs play this out..
