2004 – Kal Ho Naa Ho
When an angry Naina storms out after discovering Aman’s plan to unite her and Rohit, it’s a magically written narration that follows later. Aman takes out Rohit’s diary and pretends to read what he’s written while in reality he’s only speaking out his feelings. The emotional scene streams us into what’s going on inside of all three characters in the movie at that point. No wonder it won the best scene award that year.
