Arshi ff - A tale of love of Arnav and Khushi

Query

Hi!
I am looking for a Manan FF. I had read it long back, if any of you know kindly mention the name of book..

Manik is a CEO of Malhotra Industry. He is all alone in life. He has a friend like brother Abhi who later get Nandini and Manik married. Nandini takes care of Manik like a child. Later it is revealed that Manik is the king of Punjab and there is throne ceremony as well. Manik acts all babyish in front of Nandini..

If anybody knows kindly comment.
