Kal Ho Naa Ho (2003) on Netflix

Naina Kapur is the eldest of three and currently doing an MBA course in New York City. Her coursemate Rohit is a playboy wannabe who fails more than he succeeds, and the two befriend each other since she's one of the few women he doesn't plan to court. Naina lives with her mother and her paternal grandmother who, in essence, is your stereotypical mother-in-law. Not everything is going smoothly for the family. Their restaurant business is constantly in the red and family squabbles between the two in-laws are constant. However, the Kapur family still maintains their status quo, even if the children are unhappy about it. Enter Naina's new neighbour, Aman Mathur - a charismatic busybody who gets into everyone's face and then gets away with it. He brings a new life to the neighbourhood and slowly but surely begins to change the lives of everyone around him. He pushes people to become the best that they can be, and even gets Rohit spurred on enough to court Naina seriously. That is, until he realises that he's falling hard for Naina as well. And to complicate matters, Naina has also fallen for him.
