Yeh Jawaani Hai Deewani (2013)

Bunny, Naina, Aditi and Avi go on a trek. While Bunny, Aditi and Avi have always been close, Naina, the staid, studious girl is a last minute addition to the group. The group just wants to live life king-size. Early enough in the film, Bunny announces that marriage at 25, children at 30, retirement at 50 and then waiting for death is not how he sees his life playing out. He wants to travel the world, he wants to be free. Aditi and Avi share his thinking to a degree. But Naina is different. She is studying to be a doctor, believes in family and is a rooted young lady with traditional values. The film unravels their changing relationship when they meet many years later during Aditi's wedding.
